The fabrication of macroscopic objects from covalent organic frameworks (COFs) is challenging but of great significance to fully exploit their chem. functionality and porosity. Herein, COF/reduced graphene oxide (rGO) aerogels synthesized by a hydrothermal approach are presented. The COFs grow in situ along the surface of the 2D graphene sheets, which are stacked in a 3D fashion, forming an ultralight aerogel with a hierarchical porous structure after freeze-drying, which can be compressed and expanded several times without breaking. The COF/rGO aerogels show excellent absorption capacity (uptake of >200 g organic solvent/g aerogel), which can be used for removal of various organic liquids from water. Moreover, as active material of supercapacitor devices, the aerogel delivers a high capacitance of 269 F g-1 at 0.5 A g-1 and cycling stability over 5000 cycles. The results came from multiple reactions, including the reaction of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4COA of Formula: C9H6O6)

《Fabrication of 2D-2D heterojunction catalyst with covalent organic framework (COF) and MoS2 for highly efficient photocatalytic degradation of organic pollutants》 was written by Khaing, Kyu Kyu; Yin, Dongguang; Ouyang, Yinggen; Xiao, Songtao; Liu, Bingqi; Deng, Linlin; Li, Luqiu; Guo, Xiandi; Wang, Jun; Liu, Jinliang; Zhang, Yong. Reference of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde And the article was included in Inorganic Chemistry in 2020. The article conveys some information:

In this work, for the first time, we fabricated a novel covalent organic framework (COF)-based 2D-2D heterojunction composite MoS2/COF by a facile hydrothermal method. The results of photocatalytic degradation of TC and RhB under simulated solar light irradiation showed that the as-prepared composite exhibited outstanding catalytic efficiency compared with pristine COFs and MoS2. The significantly enhanced catalytic efficiency can be ascribed to the formation of 2D-2D heterojunction with a well-matched band position between COF and MoS2, which can effectively restrain the recombination of charge carriers and increase the light absorption as well as the sp. surface area. Moreover, the fabricated 2D-2D layered structure can effectively increase the contact area with an intimate interface contact, which greatly facilitates the charge mobility and transfer in the interfaces. This study reveals that artful integration of organic (COFs) and inorganic materials into a single hybrid with a 2D-2D interface is an effective strategy to fabricate highly efficient photocatalysts. A novel COF-based 2D-2D heterojunction composite MoS2/COF was prepared by a facile hydrothermal method. The as-prepared composite exhibited outstanding catalytic efficiency compared with pristine COFs and MoS2. The significantly enhanced catalytic efficiency is assigned to the formation of a band position of a well-matched heterojunction and the 2D-2D layered structure.

The article was written by Ghosh, Swarbhanu; Molla, Rostam Ali; Kayal, Utpal; Bhaumik, Asim; Islam, Sk. Manirul. The article contains the following contents:

CO2 fixation reactions by inserting it in reactive organic compounds are very challenging for the utilization of this abundant and harmful gas present in air and thus to mitigate this greenhouse gas responsible for global warming. This can be achieved by appropriate design of functionalized porous nanocatalysts having high surface areas and porosity and good CO2 uptake capacity. Herein, we first report the decoration of silver nanoparticles (NPs) over the surface of a covalent organic framework (COF) material TpPa-1 synthesized through the polycondensation of 2,4,6-triformylphloroglucinol (TFP) and p-phenylenediamine. The resulting material Ag@TpPa-1 was thoroughly characterized by N2 adsorption/desorption, powder X-ray diffraction (PXRD), FE-SEM, TEM, UV-Vis, FT IR and thermogravimetric techniques. This Ag NP decorated porous COF in the presence of DBU exhibited excellent catalytic activity for the synthesis of tetramic acids from a variety of propargylic amine derivatives at 60 °C under atm. pressure of carbon dioxide via formation of oxazolidinones, where CO2 acts as a C1 reagent. The Ag@TpPa-1 catalyst exhibited excellent recycling efficiency for the synthesis of tetramic acid with no leaching of Ag from the catalyst surface.2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Product Details of 34374-88-4) was used in this study.

Recommanded Product: 34374-88-4This research focused onzinc air battery iron nitrogen doped mesoporous carbon; covalent organic framework oxygen reduction electrocatalyst. The article conveys some information:

The rational design and synthesis of mesoporous functional materials is of great significance to tackle fundamental challenges in materials science and to yield practical solutions for efficient energy utilization. Here, a novel p-toluenesulfonic acid-assisted mechanochem. approach is used to prepare a silica-templated bipyridine-containing covalent organic framework (COF), which can be further converted into an iron-nitrogen-doped mesoporous carbon (mC-TpBpy-Fe) upon carbonization and template removal. The resulting mC-TpBpy-Fe exhibits a large pore volume and surface area, which significantly promote the mass transfer efficiency and increase the accessibility of the active sites, yielding a high ORR activity with a competitive half-wave potential of 0.845 V and limiting c.d. of 5.92 mA/cm2 (vs 0.852 V and 5.57 mA/cm2 for Pt/C). Application of this COF derived mesoporous carbon within a Zn-air battery revealed that it can operate in ambient conditions with a competitive discharge performance, showing its potential for practical applications.

In 2019,Journal of Membrane Science included an article by Wang, Rui; Shi, Xiansong; Zhang, Zhe; Xiao, Ankang; Sun, Shi-Peng; Cui, Zhaoliang; Wang, Yong. COA of Formula: C9H6O6. The article was titled 《Unidirectional diffusion synthesis of covalent organic frameworks (COFs) on polymeric substrates for dye separation》. The information in the text is summarized as follows:

Covalent organic frameworks (COFs) are regarded as important candidates for the preparation of advanced membranes with remarkable performances on account of their uniform and tailorable channels and good chem. stability. The development of COFs-based membranes is burgeoning, and there remains lacking of facile and mild methods to prepare to these membranes. Herein, we report on the unidirectional diffusion synthesis (UDS) of TpPa (an imine-based COFs) on com. polyvinylidene fluoride (PVDF) microfiltration substrates for the preparation of composite COFs-based membranes at room temperature The p-phenylenediamine (Pa) aqueous solution and 1,3,5-triformylphloroglucinol (Tp) n-hexane solution were sep. charged into the two sides of a diffusion cell. With the suitable solution pairs and molar ratio of two precursors, only Pa mols. can pass through the macropores of PVDF to react with Tp mols. at the phase interface formed by this solution pairs, leading to the in situ synthesis of TpPa layer on the top side of PVDF substrates. The membrane fabricated with a synthesized duration of 24 h exhibits a superior selectivity for dyes (>90%) and appreciable water permeance (60 L·m-2·h-1·bar-1). The permeance of the resultant membrane is ∼2-20 times higher than other reported membranes with comparable dye rejections. The UDS offers a facile and mild process to directly grow COFs on porous polymeric substrates to construct composite membranes capable of efficient separations of dye mols.

A functionalized magnetic covalent organic framework containing the nitro groups (Fe3O4@COF-(NO2)2) with core-shell structure was synthesized for magnetic solid phase extraction (MSPE) of six neonicotinoid insecticides residue in vegetable samples. The structure of Fe3O4@COF-(NO2)2 was investigated by various characterization techniques. The Fe3O4@COF-(NO2)2 exhibits the excellent thermal and chem. stability, high surface area (254.72 m2 g-1), total pore volume (0.19 cm3 g-1), high magnetic responsivity (27.7 emu g-1), which can be used as an ideal adsorbent for rapid isolation and enrichment of target analytes. A sensitive method was developed by using Fe3O4@COF-(NO2)2-based MSPE coupled with HPLC with UV detection. It offered good linearity within the range of 0.1-30 ng mL-1, low limits of detection (S/N = 3) of 0.02-0.05 ng mL-1. Furthermore, high enrichment factors of 170-250 for six neonicotinoid insecticides were obtained. The applicability of Fe3O4@COF-(NO2)2 is demonstrated for measuring trace neonicotinoid residues in vegetable samples with satisfactory recoveries, which ranged from 77.5 to 110.2%. The results indicated that the Fe3O4@COF-(NO2)2 microspheres offer great potential for efficient extraction of neonicotinoid insecticides from complex samples.

Zhang, Zhe; Yin, Congcong; Yang, Guanghui; Xiao, Ankang; Shi, Xiansong; Xing, Weihong; Wang, Yong published their research in Journal of Membrane Science in 2021. The article was titled 《Stitching nanosheets of covalent organic frameworks to build aligned nanopores in nanofiltration membranes for precise ion separations》.Application of 34374-88-4 The article contains the following contents:

Embedding nanofillers into polyamide (PA) matrixes is considered as a simple yet effective strategy for boosting the performances of thin-film nanocomposite (TFN) nanofiltration (NF) membranes. However, the NF performances are usually compromised by the inadequate interface compatibility between nanofillers and PA matrixes as well as the anisotropic orientation of nanofillers. Herein, we propose a distinctive fabrication strategy for TFN membranes featuring excellent compatibility and highly-aligned microstructures. The reactive covalent organic framework (COF) nanosheets are chem. stitched at oil-water interfaces to form continuous nanofilms, and the PA matrixes are then in-situ formed to encapsulate them, giving the TFN membranes. The stitched nanofilms contain two types of perpendicularly oriented pores: intrinsic apertures in COF nanosheets, and gaps among adjacent nanosheets. Together with the abundant reactive sites, the stitched nanofilms not only mediate the controllable synthesis of PA matrixes, but also are covalently fused into the matrixes. The aligned pores of the stitched nanosheets are capable of sieving salt ions, endowing TFN membranes with high separation precision and fast water permeation. This work demonstrates a strategy to control the orientation of COF nanosheets, which is highly desired in diverse fields not limited to membrane separation In the experimental materials used by the author, we found 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Application of 34374-88-4)
