Name: 2,6-PyridinedimethanolThis research focused ontransition metal benzoato imidazole pyrazole complex preparation crystal structure; pyridinemethanol pyridinedimethanol transition metal benzoato complex preparation crystal structure; collidine transition metal benzoato complex preparation crystal structure. The article conveys some information:

Structural modulation of transition metal carboxylates was studied by employing different auxiliary ligands in the reactions of metal acetates with substituted benzoic acids. Neutral transition metal benzoates [Cu(tbba)2(imH)2] (1), [Cu(tipba)2(2,4,6-collidine)2] (2), [Co(tbba)2(dmpH)2] (3), [Co(tipba)2(imH)2] (4), [M(tmba)2(pymeH)2] (M = Cu (5), Co (6) and Zn (7)), [Zn(tmba)2(pydmeH2)] (8), [Cu2(tmba)2(pydmeH2)2][(tmba)2(tmbaH)2] (9) and [Zn2(dmp)2(tbba)2(dmpH)2] (10) were isolated as products from the reaction between the resp. metal acetates and substituted benzoic acids (acids used: 4-tert-butylbenzoic acid (tbbaH), 2,4,6-triisopropylbenzoic acid (tipbaH), 2,4,6-trimethylbenzoic acid (tmbaH)) and N-donor auxiliary ligands (imidazole (imH), 3,5-dimethylpyrazole (dmpH), 2,4,6-collidine, 2-pyridinemethanol (pymeH), and pyridine-2,6-dimethanol (pydmeH2)). The new complexes were characterized by both anal. and spectroscopic methods. The mol. structures of 1-10 have further been established by single crystal x-ray diffraction studies. The complexes 1-8 are mononuclear, while compounds 9 and 10 are dinuclear due to the role of benzoic acid in 9 and pyrazolate anion as bridging ligand in 10. The geometry around the metal ion is square-planar in 1 and 2, tetrahedral in 3, 4 and 10, octahedral in 5-7 and 9 and trigonal-bipyramidal in 8. Complexes with ligands that contain addnl. functional groups such as >NH and -OH are involved in hydrogen bonding interactions. These weak interactions give 1-dimensional linear polymers or 2-dimensional sheets.2,6-Pyridinedimethanol(cas: 1195-59-1Name: 2,6-Pyridinedimethanol) was used in this study.

The author of the article were Sharma, Atul Kumar; Malineni, Jagadeesh; Box, Simon; Ghiassinejad, Sina; van Ruymbeke, Evelyne; Fustin, Charles-Andre. The article conveys some information:

We report here a synthetic platform toward mono-functionalized tridentate macrocycles based on a pyridine-2,6-bis-carboxamide motif. These macrocycles bear a variety of functional groups at the fourth position of the pyridine, giving access to a wide range of synthetic methods for further derivatization or preparation of more complex structures such as mech. interlocked mols. or polymer materials. To illustrate the potential of this family of macrocycles a series of square planar palladium complex-based pseudorotaxanes, containing different axles and functional groups on the ring, are synthesized, and then used to prepare a macro-pseudorotaxane, i.e. a polymer containing a rotaxane junction, and mech.-linked gels by a one-pot and a polyrotaxane approach. The experimental part of the paper was very detailed, including the reaction process of 2,6-Pyridinedimethanol(cas: 1195-59-1Name: 2,6-Pyridinedimethanol)

Safety of 2,6-PyridinedimethanolIn 2020 ,《Fast and Efficient Nickel(II)-catalyzed Transfer Hydrogenation of Quinolines with Ammonia Borane》 was published in Advanced Synthesis & Catalysis. The article was written by Vermaak, Vincent; Vosloo, Hermanus C. M.; Swarts, Andrew J.. The article contains the following contents:

The first Ni(II)-catalyzed transfer hydrogenation of quinolines using ammonia borane (AB) as hydrogen (H2) source was reported. An in situ generated Ni(II)-bis(pyrazolyl)pyridine pre-catalyst could hydrogenate quinoline and its derivatives in excellent yields of up to 90% at 25°C in 30 min. Spectroscopic studies revealed that a Ni(II)-hydride was responsible for the transfer hydrogenation of quinoline to 1,2,3,4-tetrahydroquinoline via a 1,4-dihydroquinoline intermediate.

《Dynamic Helicates Self-Assembly from Homo- and Heterotopic Dynamic Covalent Ligand Strands》 was written by Santoro, Antonio; Holub, Jan; Fik-Jaskolka, Marta A.; Vantomme, Ghislaine; Lehn, Jean-Marie. Category: alcohols-buliding-blocksThis research focused ontransition metal schiff base helicate complex preparation self assembly; crystal structure transition metal schiff base helicate; double-helical structures; dynamic covalent chemistry; metallo-supramolecular structures; programmed self-assembly. The article conveys some information:

The understanding and the application of reversible covalent reactions and coordination chem. together with the proper design of the mol. frameworks, allow to achieve not only well-defined output architectures but also different grades of complex behavior. In this work, the dynamic nature of the helical systems offers an addnl. level of complexity by combining self-sorting on two levels: (1) the build-up of the ligand strand constituents from their components through dynamic covalent chem.; (2) the assembly of the helicates from the ligands and the metal cations through dynamic metallo-supramol. chem. The information encoded in the ligands constituent mol. was read differently (and accurately at the same time) by metal cations that varied in the coordination algorithms. It enabled the selective formation of a specific type of helicates from a wide library of helicates formed by the possible combination of subcomponents. Ligands containing dynamic tridentate and/or bidentate binding motifs in the same strand were studied to explore the helicates self-assembly with appropriate metal cations.

The article was titled 《One-Step Construction of a Hollow Au@Bimetal-Organic Framework Core-Shell Catalytic Nanoreactor for Selective Alcohol Oxidation Reaction》, and you may find the article in ACS Applied Materials & Interfaces.Computed Properties of C7H9NO2 The information in the text is summarized as follows:

Hollow core-shell catalytic nanoreactors have received tremendous attention due to their high mass transfer in catalysis applications. Herein, we present a novel type of well-arranged, hollow core-shell nanoreactors featured with a bimetallic porous Zn/Ni-MOF-2 shell and a tiny Au nanoparticle core. The well-designed hollow Au@Zn/Ni-MOF-2 nanoreactors were constructed through the strategy of a facile one step from a rare crystal-structure transformation without any addnl. template. These nanoreactors exhibit outstanding multifunctional catalysis for a broad range of alc. oxidation under the green oxidant environment. Moreover, such hollow nanoreactors show excellent recyclability toward the selective alc. oxidation These findings might provide a promising platform for a general construct of various metal-organic framework-based hollow core-shell nanostructures and further highly augmented catalytic applications.

Picken, Stephen J.; Filonenko, Georgy A. published an article in 2021. The article was titled 《Environmentally Sensitive Luminescence Reveals Spatial Confinement, Dynamics, and Their Molecular Weight Dependence in a Polymer Glass》, and you may find the article in ACS Applied Polymer Materials.Name: 2,6-Pyridinedimethanol The information in the text is summarized as follows:

Polymer glasses have an irregular structure. Among the causes for such complexity are the chem. distinct chain end groups that are the most abundant irregularities in any linear polymer. In this work, we demonstrate that chain end induced defects allow polymer glasses to create confined environments capable of hosting small emissive mols. Using environmentally sensitive luminescent complexes, we show that the size of these confinements depends on mol. weight and can dramatically affect the photoluminescence of free or covalently bound emissive complexes. We confirm the impact of chain end confinement on the bulk glass transition in poly(Me acrylate) (pMA) and show that commonly observed Tg changes induced by the chain ends should have a structural origin. Finally, we demonstrate that the size and placement of luminescent mol. probes in pMA can dramatically affect the probe luminescence and its temperature dependence, suggesting that polymer glass is a highly irregular and complex environment, marking its difference with conventional small mol. solvents. Considering the ubiquity of luminescent glassy materials, our work lays down a blueprint for designing them with structural considerations in mind, ones where packing d. and chain end size are key factors.

The article was titled 《Rapid and visual detection of Cd2+ based on aza-BODIPY near infrared dye and its application in real and biological samples for environmental contamination screening》.Application of 1195-59-1 The article contains the following contents:

Cadmium highly toxic and hazardous, and it can adversely affect human health leading to serious disorders. Herein, a water-soluble near-IR sensor based on aza-BODIPY (1) was developed for dual determination of Cd2+ in environmental and biol. media. This sensor exhibited color change from colorless to green along with a fluorescence enhancement in the near-IR (NIR) region via photoinduced electron transfer (PET) after complexation with Cd2+. Sensor 1 can be employed in aqueous media at physiol. pH for quant. monitoring. It shows rapid response with high sensitivity (detection limit of 2.8 ppb; linear correlation over [Cd2+] 1.33 – 6.67 μM) and selectivity over potentially interfering ions. NIR sensor 1 can be used to determine [Cd2+] in living cells and environmental samples.

《Efficient FRET Approaches toward Copper(II) and Cyanide Detections via Host-Guest Interactions of Photo-Switchable [2]Pseudo-Rotaxane Polymers Containing Naphthalimide and Merocyanine Moieties》 was published in ACS Applied Materials & Interfaces in 2020. These research results belong to Ho, Feng-Cheng; Huang, Yi-Jing; Weng, Chang-Ching; Wu, Chia-Hua; Li, Yaw-Kuen; Wu, Judy I.; Lin, Hong-Cheu. Application of 1195-59-1 The article mentions the following:

A supramol. [2]pseudo-rotaxane containing a naphthalimide-based pillararene host and a spiropyran-based imidazole guest was synthesized and investigated in a semiaq. solution with 90% water fraction. Upon UV exposure, the close-form structure of nonemissive spiropyran guest could be transformed into the open-form structure of red-emissive merocyanine guest reversibly, which was utilized as a monofluorophoric sensor to detect copper(II) and cyanide ions. Moreover, the naphthalimide host as an energy donor with green photoluminescence (PL) emission at 505 nm was complexed with the merocyanine guest as an energy acceptor with red PL emission at 650 nm in 1:1 molar ratio to generate a [2]pseudo-rotaxane polymer, which was further verified by the diffusion coefficients of DOSY NMR (NMR) measurements. Due to the Förster resonance energy transfer (FRET) processes, the bifluorophoric [2]pseudo-rotaxane produced more efficient ratiometric PL behavior to induce a stronger red PL emission than that of the monofluorophoric guest; therefore, the PL sensor responses of the supramol. [2]pseudo-rotaxane toward copper(II) and cyanide ions could be further amplified via the FRET-OFF processes to turn off red PL emission of the reacted merocyanine acceptor and to recover green PL emission of the naphthalimide donor. Accordingly, the best and prominent values of the limit of detection (LOD) for the host-guest detections toward Cu2+ and CN- were 0.53 and 1.34μM, resp. The highest red MC emission with the optimum FRET processes of [2]pseudo-rotaxane was maintained around room temperature (20-40°C) in wide pH conditions (pH = 3-13), which can be utilized in the cell viability tests to prove the nontoxic and remarkable biomarker of [2]pseudo-rotaxane to detect Cu2+ and CN- in living cells. The developed FRET-OFF processes with ratiometric PL behavior of the bifluorophoric supramol. [2]pseudo-rotaxane polymer will open a new avenue to the future applications of chemo- and biosensors.
