2023年9月6日 · We began by synthesizing monodisperse, submicrometer-sized colloidal spherical particles of the imine-linked TAPB-BTCA-COF. Both 1,3,5-tris(4-aminophenyl)benzene (TAPB) (0.04 mmol) and benzene-1,3,5-tricarbaldehyde (BTCA) (0.04 mmol) were first dissolved in 5 mL of acetonitrile containing acetic acid (AcOH) (12 M).

2015年9月21日 · We developed a novel structure, TPB-DMTP-COF (TPB, triphenylbenzene; DMTP, dimethoxyterephthaldehyde), that possesses C3 -TPB vertices and electron-donating (lone pairs on the oxygen)...

In this study, we proposed a Z-scheme heterojunction WO /covalent organic framework (Tp–TAPB) that can accelerate the separation and charge transfer at the interface and retain the strong oxidative and reductive ability of WO and Tp–TAPB.

2020年11月4日 · TPB-TP-COF, the homolog to TPB-DMTP-COF but without methoxy groups, and TPB-DHTP-COF (DHTP, dihydroxy terephthaldehyde) with -OH functionalities that permit intramolecular H-bonding, both exhibited lower chemical stabilities, revealing the pivotal stabilization effects of methoxy groups.

2023年5月11日 · Herein, we describe the fabrication of solvent-resistant COF membranes with customized pore sizes for the effective recovery of homogeneous photocatalysts. To demonstrate the broad applicability...

Herein, an aminal‐linked covalent organic framework (COF) membrane featuring a regular long‐range pore size of 7 Å and achieving superior ion selectivity is reported, in which a uniform COF...

2021年12月1日 · In this work, TAPB-DHTA COF films were grown on sapphire substrates and meticulously transferred onto suspended sample stages of the SEM. Mechanical testing for fracture strength and Young’s modulus of COF TAPB …

通过固-汽界面反应合成高度有序的单层二维共价有机框架（scofs），具有亚胺键的蜂窝状结构，为分子电子学和光电子设备领域提供新合成策略。chemsoon-tapb-tpa cof专业供应商

the resulting TAPB-BTCA-COF particles exhibited a lower colloidal stability, which precluded their ability to form ordered assembled structures. Thus, unreacted linkers are cardinal for stabilizing TAPB-BTCA-COF colloids and for their subse-quent …

TAPB是一种多环芳香烃化合物，其六氟苯并环和四甲基基团赋予了分子一定的稳定性和特殊的电子结构。 在TAPB-TP-COF中，TAPB作为COF的主要单体之一，为材料提供了特定的结构和性质。 TP是一种含氮杂环化合物，具有蒽酮骨架和四甲基基团。 在TAPB-TP-COF中，TP是另一种主要单体，与TAPB共同形成COF的重复单元。 TAPB和TP单体通过共价键连接形成COF的重复单元，构建了COF的有序结构。 COF的有序孔道结构和高比表面积使其具有吸附和分离性能。 …
