The information in the text is summarized as follows:

Photocatalytic reduction of CO2 into energy-rich carbon compounds has attracted increasing attention. However, it is still a challenge to selectively and effectively convert CO2 to a desirable reaction product. Herein, we report a design of a synergistic photocatalyst for selective reduction of CO2 to CO by using a covalent organic framework bearing single Ni sites (Ni-TpBpy), in which electrons transfer from photosensitizer to Ni sites for CO production by the activated CO2 reduction under visible-light irradiation Ni-TpBpy exhibits an excellent activity, giving a 4057μmol g-1 of CO in a 5 h reaction with a 96% selectivity over H2 evolution. More importantly, when the CO2 partial pressure was reduced to 0.1 atm, 76% selectivity for CO production is still obtained. Theor. calculations and exptl. results suggest that the promising catalytic activity and selectivity are ascribed to synergistic effects of single Ni catalytic sites and TpBpy, in which the TpBpy not only serves as a host for CO2 mols. and Ni catalytic sites but also facilitates the activation of CO2 and inhibits the competitive H2 evolution.

Covalent organic frameworks (COFs) with well-tailored channels are able to accommodate ions and offer their conduction pathway. However, due to strong Coulombic interaction and the lack of transport medium, directly including lithium salts into the channels of COFs results in limited ion transport capability. Herein, we propose a strategy of incorporating low-mol.-weight polyethylene glycol (PEG) into COFs with anionic, neutral, or cationic skeletons to accelerate Li+ conduction. The PEG confined in the well-aligned channels retains high flexibility and Li+ solvating ability. The ion conductivity of PEG included in a cationic COF can reach 1.78 × 10-3 S cm-1 at 120 °C. The simplicity of this strategy as well as the diversity of crystalline porous materials holds great promise to design high-performance all-solid-state ion conductors.

A metal-insulator-semiconductor (MIS) photosystem based on covalent organic framework (COF) semiconductors was designed for robust and efficient hydrogen evolution under visible-light irradiation A maximal H2 evolution rate of 8.42 mmol h-1 g-1 and a turnover frequency of 789.5 h-1 were achieved by using a MIS photosystem prepared by electrostatic self-assembly of polyvinylpyrrolidone (PVP) insulator-capped Pt nanoparticles (NPs) with the hydrophilic imine-linked TP-COFs having =C=O-H-N= hydrogen-bonding groups. The hot π-electrons in the photoexcited n-type TP-COF semiconductors can be efficiently extracted and tunneled to Pt NPs across an ultrathin PVP insulating layer to reduce protons to H2. Compared to the Schottky-type counterparts, the COF-based MIS photosystems give a 32-fold-enhanced carrier efficiency, attributed to the combined enhancement of photoexcitation rate, charge separation, and oxidation rate of holes accumulated in the valence band of the TP-COF semiconductor.

Category: alcohols-buliding-blocks. The article was titled 《Solvent-Free, Single Lithium-Ion Conducting Covalent Organic Frameworks》. The information in the text is summarized as follows:

Porous crystalline materials such as covalent organic frameworks and metal-organic frameworks have garnered considerable attention as promising ion conducting media. However, most of them addnl. incorporate lithium salts and/or solvents inside the pores of frameworks, thus failing to realize solid-state single lithium-ion conduction behavior. Herein, we demonstrate a lithium sulfonated covalent organic framework (denoted as TpPa-SO3Li) as a new class of solvent-free, single lithium-ion conductors. Benefiting from well-designed directional ion channels, a high number d. of lithium-ions, and covalently tethered anion groups, TpPa-SO3Li exhibits an ionic conductivity of 2.7 × 10-5 S cm-1 with a lithium-ion transference number of 0.9 at room temperature and an activation energy of 0.18 eV without addnl. incorporating lithium salts and organic solvents. Such unusual ion transport phenomena of TpPa-SO3Li allow reversible and stable lithium plating/stripping on lithium metal electrodes, demonstrating its potential use for lithium metal electrodes.

《Nanoparticle Size-Fractionation through Self-Standing Porous Covalent Organic Framework Films》 was published in Angewandte Chemie, International Edition in 2020. These research results belong to Dey, Kaushik; Kunjattu H., Shebeeb; Chahande, Anurag M.; Banerjee, Rahul. Name: 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde The article mentions the following:

Covalent organic frameworks (COFs) have attracted attention due to their ordered pores leading to important industrial applications like storage and separation Combined with their modular synthesis and pore engineering, COFs could become ideal candidates for nanosepns. However, the fabrication of these microcrystalline powders as continuous, crack-free, robust films remains a challenge. Herein, we report a simple, slow annealing strategy to construct centimeter-scale COF films (Tp-Azo and Tp-TTA) with micrometer thickness. The as-synthesized films are porous (SABET = 2033 m2 g-1 for Tp-Azo) and chem. stable. These COFs have distinct size cut-offs (ca. 2.7 and ca. 1.6 nm for Tp-Azo and Tp-TTA, resp.), which allow the size-selective separation of gold nanoparticles. Unlike, other conventional membranes, the durable structure of the COF films allow for excellent recyclability (up to 4 consecutive cycles) and easy recovery of the gold nanoparticles from the solution In addition to this study using 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde, there are many other studies that have used 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Name: 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde) was used in this study.

《Phenazine-Based Covalent Organic Framework Cathode Materials with High Energy and Power Densities》 was written by Vitaku, Edon; Gannett, Cara N.; Carpenter, Keith L.; Shen, Luxi; Abruna, Hector D.; Dichtel, William R.. Formula: C9H6O6 And the article was included in Journal of the American Chemical Society in 2020. The article conveys some information:

Redox-active covalent organic frameworks (COFs) are promising materials for energy storage devices because of their high d. of redox sites, permanent and controlled porosity, high surface areas, and tunable structures. However, the low electrochem. accessibility of their redox-active sites has limited COF-based devices either to thin films (<250 nm) grown on conductive substrates or to thicker films (1 μm) when a conductive polymer is introduced into the COF pores. Elec. energy storage devices constructed from bulk microcrystalline COF powders, eliminating the need for both thin-film formation and conductive polymer guests, would offer both improved capacity and potentially scalable fabrication processes. Here we report on the synthesis and electrochem. evaluation of a new phenazine-based 2D COF (DAPH-TFP COF), as well as its composite with poly(3,4-ethylenedioxythiophene) (PEDOT). Both the COF and its PEDOT composite were evaluated as powders that were solution-cast onto bulk electrodes serving as current collectors. The unmodified DAPH-TFP COF exhibited excellent elec. access to its redox sites, even without PEDOT functionalization, and outperformed the PEDOT composite of our previously reported anthraquinone-based system. Devices containing DAPH-TFP COF were able to deliver both high-energy and high-power densities, validating the promise of unmodified redox-active COFs that are easily incorporated into elec. energy storage devices. In addition to this study using 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde, there are many other studies that have used 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Formula: C9H6O6) was used in this study.

The title of the article was 《Chelating effect between uranyl and pyridine N containing covalent organic frameworks: A combined experimental and DFT approach》.Product Details of 34374-88-4 The author mentioned the following in the article:

Covalent organic frameworks (COFs) are promising adsorbents for removing heavy metal ions, and have high crystallinity, a porous structure, and conjugated stability. N-containing functional groups are known to have great affinity for uranyl ions. In this work, to explore the peculiarity of the pyridine N structure as an efficient adsorbent, we chose 2,2′-dipyridine-5,5′-diamine (Bpy) and pyridine-2,5′-diamine (Py) as the core skeletons, and 1,3,5-triformylphloroglucinol (Tp) as the linker to synthesize two crystalline and stable N-containing COFs named TpBpy and TpPy, resp., through a facile solvothermal method. Characterization results demonstrated that TpBpy and TpPy possessed regularly growing pore sizes, large sp. surface areas and relatively strong thermal resistances. The results of batch experiments showed that both COF materials were capable of the effective removal of uranyl with uptake capacities of 115.45 mg g-1 and 291.79 mg g-1, resp. In addition, d. functional theory (DFT) simulations highlighted the beneficial chelation effect of the double N structure in pyridine monomers for removing uranyl ions. Combining systematic exptl. and theor. analyses, the adsorption process and interaction mode of porous COFs and UO2+2 were revealed, to provide predictable support for the application of pyridine N-containing COFs in the field of environmental remediation.2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Product Details of 34374-88-4) was used in this study.

Product Details of 34374-88-4In 2021 ,《Self-Assembly-Driven Nanomechanics in Porous Covalent Organic Framework Thin Films》 was published in Journal of the American Chemical Society. The article was written by Dey, Kaushik; Bhunia, Surojit; Sasmal, Himadri Sekhar; Reddy, C. Malla; Banerjee, Rahul. The article contains the following contents:

Nanomechanics signifies a key tool to interpret the macroscopic mech. properties of a porous solid in the context of mol.-level structure. However, establishing such a correlation has proved to be significantly challenging in porous covalent organic frameworks (COFs). Structural defects or packing faults within the porous matrix, poor understanding of the crystalline assembly, and surface roughness are critical factors that contribute to this difficulty. In this regard, we have fabricated two distinct types of COF thin films by controlling the internal order and self-assembly of the same building blocks. Interestingly, the defect d. and the nature of supramol. interactions played a significant role in determining the corresponding thin films’ stress-strain behavior. Thin films assembled from nanofibers (~1-2μm) underwent large deformation on the application of small external stress (Tp-Azofiber film: E ≈ 1.46 GPa; H ≈ 23 MPa) due to weak internal forces. On the other hand, thin films threaded with nanospheres (~600 nm) exhibit a much stiffer and harder mech. response (Tp-Azosphere film: E ≈ 15.3 GPa; H ≈ 66 MPa) due to strong covalent interactions and higher crystallinity. These porous COF films further exhibited a significant elastic recovery (~80%), ideal for applications dealing with shock-resistant materials. This work provides in-depth insight into the fabrication of industrially relevant crystalline porous thin films and membranes by addressing the previously unanswered questions about the mech. constraints in COFs. In the part of experimental materials, we found many familiar compounds, such as 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Product Details of 34374-88-4)

《2D-2D SnS2/Covalent Organic Framework Heterojunction Photocatalysts for Highly Enhanced Solar-Driven Hydrogen Evolution without Cocatalysts》 was written by Shang, Dandan; Li, Di; Chen, Biyi; Luo, Bifu; Huang, Yuanyong; Shi, Weidong. Safety of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehydeThis research focused ontin sulfide covalent organic framework heterojunction photocatalyst hydrogen evolution. The article conveys some information:

Covalent organic frameworks (COFs) are a category of promising materials in the field of solar-driven hydrogen (H2) evolution, but their applications are limited by the speedy recombination of photoinduced charge carriers and the absorption of marginal visible light. Herein, a 2D-2D SnS2/TpPa-1-COF heterojunction photocatalyst was prepared via a one-step hydrothermal route to relieve the abovementioned shortcomings. The results show that the obtained 2D-2D SnS2/TpPa-1-COF heterojunctions not only speed up the separation of photogenerated charge carriers but also facilitate the H2 production kinetics and expand the range of visible light response to orange light (600 nm). Especially, the maximum photocatalytic H2 production rate of the 2D-2D SnS2/TpPa-1-COF heterojunction without the addition of cocatalyst Pt reaches 37.11μmol h-1, which is 21.7-fold and 2-fold higher than those of individual TpPa-1-COF and 3 wt % Pt/TpPa-1-COF, resp. This work indicates that the synthesis of cheap COF-based photocatalysts for high-efficiency solar energy utilization is a feasible approach to boost the photocatalytic H2 performance. In addition to this study using 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde, there are many other studies that have used 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Safety of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde) was used in this study.

《Ultrathin Two-Dimensional Membranes Assembled by Ionic Covalent Organic Nanosheets with Reduced Apertures for Gas Separation》 was written by Ying, Yunpan; Tong, Minman; Ning, Shoucong; Ravi, Sai Kishore; Peh, Shing Bo; Tan, Swee Ching; Pennycook, Stephen John; Zhao, Dan. Related Products of 34374-88-4This research focused onultrathin membrane assembled ionic covalent organic nanosheet aperture gas. The article conveys some information:

Covalent organic frameworks (COFs) are a promising category of porous materials possessing extensive chem. tunability, high porosity, ordered arrangements at a mol. level, and considerable chem. stability. Despite these advantages, the application of COFs as membrane materials for gas separation is limited by their relatively large pore apertures (typically >0.5 nm), which exceed the sieving requirements for most gases whose kinetic diameters are less than 0.4 nm. Herein, we report the fabrication of ultrathin two-dimensional (2D) membranes through layer-by-layer (LbL) assembly of two kinds of ionic covalent organic nanosheets (iCONs) with different pore sizes and opposite charges. Because of the staggered packing of iCONs with strong electrostatic interactions, the resultant membranes exhibit features of reduced aperture size, optimized stacking pattern, and compact dense structure without sacrificing thickness control, which are suitable for mol. sieving gas separation One of the hybrid membranes, TpEBr@TpPa-SO3Na with a thickness of 41 nm, shows a H2 permeance of 2566 gas permeation units (GPUs) and a H2/CO2 separation factor of 22.6 at 423 K, surpassing the recent Robeson upper bound along with long-term hydrothermal stability. This strategy provides not only a high-performance H2 separation membrane candidate but also an inspiration for pore engineering of COF or 2D porous polymer membranes.
