作者通过将pdi单元整合到cof中，构建了具有明确晶体结构的pdi-pda，通过精确调控分子间聚集和电子转移动力学，显著提高了光催化氧化效率。 实验部分：

2023年12月1日 · Constructing the heterojunction by using covalent organic frameworks (COFs) is an effective way to promote photocatalytic activity. Herein, we designed and constructed different ratios of PDI/COFs hybrid materials by solvothermal method, denoted as PDI/TAPB-PDA (TAPB = 1,3,5-tris (4-aminophenyl)benzene, PDA = terephthaldehyde) composite.

2020年9月7日 · 为了深入理解pdi可见光催化木质素解聚的机理，作者进行了活性物种捕获实验，证明光激发电子和自由基同时主导β-o-4键断裂过程。 同时还通过光谱分析验证了PDI作为反应体系中唯一可见光吸收单元。

2019年4月23日 · Electronic interaction among the building blocks of a 2D COF and inter-layer π–π interaction among the stacked layers of COFs provide efficient pathways for photogenerated charge carriers.

近年来，二维共价有机框架（2d-cof）在催化、气体存储/分离、固态电池、传感和光电/光伏等领域引起了广泛兴趣。通常，2d-cof合成主要由共价键合单层的横向生长和通过2d层的可控性π堆叠程度较低的框架的垂直延伸所决定。

Ultrafast charge transfer in a D–A COF, condensed from 3,4,9,10-perylenetetracarboxylic acid diimide (PDI) and porphyrin building blocks, could be observed with femtosecond TA spectroscopy and further studied by non-adiabatic molecular dynamics calculations.

Here, we designed and synthesized a novel polyimide COF, namely, TAPA-PDI-COF, with abundant C=O groups, which has been successfully employed as high-performance solid electrolytes by doping TAPA-PDI-COF and succinonitrile (SN).
