摘要

在本研究中，我们将羟基（COF-JLU71）和甲氧基（COF-JLU72）官能团加入到4,4',4'' -（1,9-二氢芘-1,3,6,8-四基）四苯甲醛的二维框架中，并与4,4'-（苯并[c][1,2,5]噻二唑-4,7-二基）苯胺通过席夫碱缩合合成了两个亲水性COFs。比较了它们的结构特征，发现这些修饰有利于氢键网络的构建、光结构的调整、亲水性的增强以及光催化水分解效率的提高。

Hydrophilic Engineering of Pyrene-Based COFs for Enhanced Photocatalytic Hydrogen Evolution.

In this study, we incorporated hydroxyl (COF-JLU71) and methoxy (COF-JLU72) functional groups into the 2D framework of 4,4',4'',4'''-(1,9-dihydropyrene-1,3,6,8-tetrayl)tetrabenzaldehyde and synthesized two hydrophilic COFs by Schiff base condensation with 4,4'-(benzo[c][1,2,5]thiadiazole-4,7-diyl) aniline. Their structural features were compared, and it was found that such modifications are beneficial for the construction of hydrogen bond networks, the tuning of photostructures, the enhancement of hydrophilicity, and the improvement of photocatalytic water splitting efficiency.
