In recent years, sequence-controlled side-chain liquid crystal polymers (SCLCPs) have gained extensive interest because mesogenic units with different lengths and distributions can form various ordered sequences, which further endow LCP materials with diverse functions. In this manuscript, a side-chain side-on maleimide-containing monomer 2,5-bis-(4-butoxy-benzoyloxy)-benzoic acid 6-(2,5-dioxo-2,5-dihydro-pyrrol-1-yl)-hexyl ester (Y1801) and a side-chain end-on styrene-containing monomer 4′-[6-(4-vinyl-phenoxy)-hexyloxy]-biphenyl-4-carbonitrile (Y1802) are combined in one single macromol. chain and orderly polymerized in an alternative sequence to form an alternating copolymer Poly(Y1801-alt-Y1802). The chem. structure and alternating sequence of Poly(Y1801-alt-Y1802) are confirmed by GPC and NMR techniques. The combination of DSC, POM, and WAXS data indicates that, although the side-on homopolymer PY1801 and the end-on homopolymer PY1802 both exhibit the nematic phase, their alternating copolymer Poly(Y1801-alt-Y1802) shows an interdigitated smectic A phase, a compromised mol. arrangement instead. In addition, a strong fluorescence emission of Poly(Y1801-alt-Y1802) is observed, which might provide this novel alternating-structured liquid crystal polymer with potential applications in luminescent materials and devices. After reading the article, we found that the author used 6-Aminohexan-1-ol(cas: 4048-33-3Name: 6-Aminohexan-1-ol)

Fu, Linxia’s team published research in Macromolecules (Washington, DC, United States) in 2019 | CAS: 4048-33-3

In 2019,Macromolecules (Washington, DC, United States) included an article by Fu, Linxia; Yang, Jixing; Dong, Liqi; Yu, Huitao; Yan, Qinghai; Zhao, Fulai; Zhai, Fei; Xu, Yunhua; Dang, Yanfeng; Hu, Wenping; Feng, Yiyu; Feng, Wei. SDS of cas: 4048-33-3. The article was titled 《Solar Thermal Storage and Room-Temperature Fast Release Using a Uniform Flexible Azobenzene-Grafted Polynorborene Film Enhanced by Stretching》. The information in the text is summarized as follows:

Deformation-controlled solar thermal storage and release are important for thermal management of dynamic systems. However, few researchers have examined cyclic solid-state solar thermal utilization with different deformations. A uniform flexible stretchable solar thermal fuel film is presented using polynorbornene-templated azobenzene (PNB-Azo) with ring-opening metathesis polymerization and covalent grafting. This film has a high degree of isomerization and good storage stability compared to push-pull electronic interaction. At 20% strain rate, the film combines high-degree photocharging (85%), high energy d. (49.0 Wh kg-1), and high rate of heat release induced by blue light (475 nm) at room temperature Greater free volume improves isomerization and the first-order kinetic constant is increased by 1 order of magnitude. Reversible elec.-driven dynamic stretching during charging and discharging enables PNB-Azo””fingers”” to release heat more rapidly than static stretched film, resulting in a temperature increase of 1.5 °C. The result indicates that PNB-Azofilm can be used as a high-power dynamic solar heat source by controlling the deformation. The experimental part of the paper was very detailed, including the reaction process of 6-Aminohexan-1-ol(cas: 4048-33-3SDS of cas: 4048-33-3)

McCann, Scott D.’s team published research in Journal of the American Chemical Society in 2020 | CAS: 4048-33-3

《Development of an Aryl Amination Catalyst with Broad Scope Guided by Consideration of Catalyst Stability》 was published in Journal of the American Chemical Society in 2020. These research results belong to McCann, Scott D.; Reichert, Elaine C.; Arrechea, Pedro Luis; Buchwald, Stephen L.. Computed Properties of C6H15NO The article mentions the following:

The authors have developed a new dialkylbiaryl monophosphine ligand, GPhos, that supports a palladium catalyst capable of promoting carbon-nitrogen cross-coupling reactions between a variety of primary amines and aryl halides; in many cases, these reactions can be carried out at room temperature The reaction development was guided by the idea that the productivity of catalysts employing BrettPhos-like ligands is limited by their lack of stability at room temperature Specifically, it was hypothesized that primary amine and N-heteroaromatic substrates can displace the phosphine ligand, leading to the formation of catalytically dormant palladium complexes that reactivate only upon heating. This notion was supported by the synthesis and kinetic study of a putative off-cycle Pd complex. Consideration of this off-cycle species, together with the identification of substrate classes that are not effectively coupled at room temperature using previous catalysts, led to the design of a new dialkylbiaryl monophosphine ligand. An Ot-Bu substituent was added ortho to the dialkylphosphino group of the ligand framework to improve the stability of the most active catalyst conformer. To offset the increased size of this substituent, the authors also removed the para i-Pr group of the non-phosphorus-containing ring, which allowed the catalyst to accommodate binding of even very large α-tertiary primary amine nucleophiles. In comparison to previous catalysts, the GPhos-supported catalyst exhibits better reactivity both under ambient conditions and at elevated temperatures Its use allows for the coupling of a range of amine nucleophiles, including (1) unhindered, (2) five-membered-ring N-heterocycle-containing, and (3) α-tertiary primary amines, each of which previously required a different catalyst to achieve optimal results. The experimental part of the paper was very detailed, including the reaction process of 6-Aminohexan-1-ol(cas: 4048-33-3Computed Properties of C6H15NO)

Ongaro, Alberto’s team published research in Nanomedicine (New York, NY, United States) in 2022 | CAS: 4048-33-3

In 2022,Ongaro, Alberto; Violatto, Martina Bruna; Casarin, Elisabetta; Pellerani, Isabella; Marchini, Gloria; Ribaudo, Giovanni; Salmona, Mario; Carbone, Marco; Passoni, Alice; Gnodi, Elisa; Schiavon, Elisa; Mattarei, Andrea; Barisani, Donatella; Invernizzi, Pietro; Bigini, Paolo; Morpurgo, Margherita published an article in Nanomedicine (New York, NY, United States). The title of the article was 《The mode of dexamethasone decoration influences avidin-nucleic-acid-nano-assembly organ biodistribution and in vivo drug persistence》.Category: alcohols-buliding-blocks The author mentioned the following in the article:

Avidin-Nucleic-Acid-NanoASsemblies (ANANAS) possess natural tropism for the liver and, when loaded with dexamethasone, reduce clin. progression in an autoimmune hepatitis murine model. Here, we investigated the linker chem. (hydrazide-hydrazone, Hz-Hz, or carbamate hydrazide-hydrazone, Cb-Hz bond) and length (long, 5 kDa PEG, or short, 5-6 carbons) in biotin-dexamethasone conjugates used for nanoparticle decoration through in vitro and in vivo studies. All four newly synthesized conjugates released the drug at acidic pH only. In vitro, the Hz-Hz and the PEG derivatives were less stable than the Cb-Hz and the short chain ones, resp. Once injected in healthy mice, dexamethasone location in the PEGylated ANANAS outer layer favors liver penetration and resident macrophages uptake, while drug Hz-Hz, but not Cb-Hz, short spacing prolongs drug availability. In conclusion, the tight modulation of ANANAS decoration can significantly influence the host interaction, paving the way for the development of steroid nanoformulations suitable for different pharmacokinetic profiles. In the experiment, the researchers used many compounds, for example, 6-Aminohexan-1-ol(cas: 4048-33-3Category: alcohols-buliding-blocks)

Kwon, Na Yeon’s team published research in Macromolecules (Washington, DC, United States) in 2022 | CAS: 4048-33-3

In 2022,Kwon, Na Yeon; Kim, Youngseo; Kataria, Meenal; Park, Su Hong; Cho, Seunguk; Harit, Amit Kumar; Woo, Han Young; Cho, Min Ju; Park, Sungnam; Choi, Dong Hoon published an article in Macromolecules (Washington, DC, United States). The title of the article was 《Donor-σ-Acceptor Dyad-Based Polymers for Portable Sensors: Controlling Photoinduced Electron Transfer via Tuning the Frontier Molecular Orbital Energies of Acceptors》.Product Details of 4048-33-3 The author mentioned the following in the article:

In this study, we synthesized three novel aromatic imide-based conjugated donor(D)-σ-acceptor (A) dyad-based polymers showing different photophys. properties. These D-σ-A dyad-based polymers (e.g., BDTBT-NI, BDTBT-NDI, and BDTBT-PDI) consist of the same conjugated donor main chains (benzodithiophene-bithiophene (BDTBT)) and side chains bearing different imide acceptors (naphthalimide (NI), naphthalene diimide (NDI), or perylenediimide (PDI)). The photophys. and electrochem. characteristics of the three polymers were studied using various methods, including UV-visible absorption, steady-state fluorescence, and time-resolved fluorescence experiments as well as cyclic voltammetry. As the acceptor strength of the side chain was increased, photoinduced electron transfer from the donor backbone to the acceptor side-chain moiety was found to occur more effectively. Among the three polymers, BDTBT-PDI was found to be used as an efficient extractor and portable naked-eye sensing probe for Fe2+ ions; notably, it exhibited a “”turn-on”” fluorescence response with a detection limit at a picomolar concentration The BDTBT-PDI:Fe2+ complex was also used for ultrasensitive detection of spermine (with a Stern-Volmer constant of 6.7 × 106 M-1) in urine samples and was established as an efficient portable test kit for the real-time detection of spermine in the vapor released from fermented food samples. Finally, the “”on-off”” fluorescence behavior of BDTBT-PDI in the presence of Fe2+ and spermine enabled us to develop mol. logic gates using this polymer. In the part of experimental materials, we found many familiar compounds, such as 6-Aminohexan-1-ol(cas: 4048-33-3Product Details of 4048-33-3)

Amouzadeh Tabrizi, Mahmoud’s team published research in Sensors and Actuators, B: Chemical in 2021 | CAS: 4048-33-3

Amouzadeh Tabrizi, Mahmoud; Nazari, Leila; Acedo, Pablo published their research in Sensors and Actuators, B: Chemical in 2021. The article was titled 《A photo-electrochemical aptasensor for the determination of severe acute respiratory syndrome coronavirus 2 receptor-binding domain by using graphitic carbon nitride-cadmium sulfide quantum dots nanocomposite》.Application In Synthesis of 6-Aminohexan-1-ol The article contains the following contents:

Herein, a photoelectrochem. aptasensor for the quant. measurement of the severe acute respiratory syndrome coronavirus-2 receptor-binding domain (Sars-Cov-2 RBD) has been reported for the first time. For this purpose, first, graphitic carbon nitride and (gC3N4) and cadmium sulfide (CdS) quantum dots were fabricated and characterized. After that, gC3N4 and CdS were mixed well. The fabricated nanomaterials were characterized by scanning transmission electron microscopy. Then, the CdS QDs-gC3N4 nanocomposite was added to the solution containing chitosan as an amine-rich polymer to generate a Chitosan/CdS-gC3N4 nanocomposite. Subsequently, the surface of the ITO electrode was modified with Chitosan/CdS-gC3N4. After that, the amine-terminal aptamer probes were immobilized on the surface of the Chitosan/CdS QDs-gC3N4/ITO electrode by using glutaraldehyde as an amine-amine crosslinker. The electrochem. performances of the electrodes were studied using cyclic voltammetry (CV), electrochem. Impedance Spectroscopy (EIS), and photo-electrochem. (PEC). The surface coverage of the immobilized aptamer probe was founded to be 26.2 pmol.cm-2. The obtained results demonstrated that the proposed photo-electrochem. aptasensor can be used for the measurement of Sars-Cov-2 RBD within 0.5-32.0 nM. The limit of detection (LOD) was obtained to be 0.12 nM (at 3σ/slope). The affinity of the Aptamer/Chitosan/CdS QDs-gC3N4/ITO was also founded to be 3.4 nM by using Langmuir-typical adsorption systems. The proposed photo-electrochem. aptasensor was applied for the measurement of the spiked Sars-Cov-2 RBD in human saliva samples at two concentrations The effect of the interfering biomaterials such as human IgG human IgA, human IgM, and human serum albumin was also studied. The experimental process involved the reaction of 6-Aminohexan-1-ol(cas: 4048-33-3Application In Synthesis of 6-Aminohexan-1-ol)

HPLC of Formula: 4048-33-3In 2020 ,《Crucial Role of the Spacer in Tuning the Length of Self-Assembled Nanorods》 appeared in Macromolecules (Washington, DC, United States). The author of the article were Han, Shuaiyuan; Mellot, Gaelle; Pensec, Sandrine; Rieger, Jutta; Stoffelbach, Francois; Nicol, Erwan; Colombani, Olivier; Jestin, Jacques; Bouteiller, Laurent. The article conveys some information:

Polymeric supramol. nanorods were prepared in toluene by self-assembly of tris(urea) stickers connected on both sides through alkyl spacers of different lengths to short polystyrene (PS) arms. Several tris(urea) initiators or chain transfer agents were synthesized straightforwardly and used to grow well-defined PS arms via atom transfer radical polymerization (ATRP) or reversible addition fragmentation chain transfer (RAFT) polymerization Self-assembly was investigated by means of Fourier-transform IR (FTIR) spectroscopy and light/neutron scattering. A dramatic impact of the spacer separating the tris(urea) sticker from the PS arms on the extent of self-assembly was observed in toluene as long as the d.p. of the PS arms (x) was kept short (x ~10). Indeed, supramol. nanorods several hundreds of nanometers in length for a few nanometers in radius were obtained with a spacer consisting of nine atoms, whereas five times shorter nanorods were obtained for a spacer of only five atoms, and spherical particles were found in the absence of any spacer, all other parameters remaining unchanged. These results reveal the possibility to tune the length of polymer-decorated supramol. nanorods with minimal modification of the assembling sticker and without affecting the functionality of the rods. The experimental process involved the reaction of 6-Aminohexan-1-ol(cas: 4048-33-3HPLC of Formula: 4048-33-3)

Martin, Ian J.’s team published research in Macromolecules (Washington, DC, United States) in 2020 | CAS: 4048-33-3

Related Products of 4048-33-3In 2020 ,《Templated Supramolecular Structures of Multichromic, Multiresponsive Perylene Diimide-Polydiacetylene Films》 was published in Macromolecules (Washington, DC, United States). The article was written by Martin, Ian J.; Shih, Kuo-Chih; Nieh, Mu-Ping; Kasi, Rajeswari M.. The article contains the following contents:

We report a detailed synthesis and characterization of novel polymeric supramol. structures composed of semiconducting perylene diimide (PDI)-imidazole templates of varying methylene spacer length (n = 3, 4, and 6) hydrogen-bonded to a conjugated polymer backbone of acid-functionalized polydiacetylene (PDA), 10,12 pentacosadiynoic acid. First, a combination of mol. and morphol. characterization tools confirmed that the templated supramol. structures are a result of the synergistic effect of intermol. PDI π-π stacking coupled with noncovalent imidazole-acid interactions. Second, a simple and scalable solid-state polymerization of the drop-cast films by UV radiation delivers multichromic, multiresponsive films capable of unique phase/morphol.-switching properties with a high degree of local ordering. Thermal studies by differential scanning calorimetry and morphol. studies by wide- and small-angle X-ray scattering (WAXS/SAXS, resp.) show dramatic morphol. effects and trends in crystallinity with methylene spacer group extension. Furthermore, UV-vis studies displayed an unusual PDA “”purple phase”” transition, which was addnl. verified by SAXS as a coexistence of previously known red- and blue-phase PDA. Finally, the polymerized drop-cast films displayed reversible thermo- and solvatochromic responses after a second treatment of UV radiation and addnl. UV-thermal cycling revealed the extent of reversibility. The results came from multiple reactions, including the reaction of 6-Aminohexan-1-ol(cas: 4048-33-3Related Products of 4048-33-3)

And the article was published in Journal of Photochemistry and Photobiology, A: Chemistry in 2019. Electric Literature of C6H15NO The author mentioned the following in the article:

We report the synthesis, characterization, photophys. and photochem. properties of two novel perylenebisimide-fullerene dyads (7 and 8) bearing one or two perylenebisimide (PBI) units as light harvester and a fullerene as spin converter. The mol. structures of all synthesized compounds were elucidated by elemental analyses, mass spectrometry, FT-IR, 1H and 13C NMR techniques. Their optical properties were investigated by UV-vis absorption and 2D/3D fluorescence emission spectroscopies. The photochem. studies via direct and indirect method endorsed PBI-fullerene dyads (7 and 8) as efficient heavy atom free tripletphotosensitizers whereas perylene derivatives did not exhibit any singlet oxygen production The PBI-fullerene dyads exhibit excellent singlet oxygen quantum yields of 0.93 and 0.95. The PBI-fullerene dyads (7 and 8) are also able to use in the photooxidation of 1,5-dihydroxynaphtalene (DHN) to produce juglone and are recognized as stronger than MB as conventional triplet photosensitizers. The results came from multiple reactions, including the reaction of 6-Aminohexan-1-ol(cas: 4048-33-3Electric Literature of C6H15NO)
