Abstract

A crystalline, bi-photoelectric structural unit 2D periodic square lattice covalent organic framework was designed and target synthesized by the Schiff base condensation between 1,1,2,2-tetra(4-formyl-(1,1′-biphenyl)) ethene and 5,10,15,20-tetrakis(4-amino phenyl)-21H,23H-porphyrin with AA stacking structures, named as TP-COF. The TP-COF exhibited good photoelectric response combined with good crystallinity and high specific surface area (1812 m² g⁻¹). TP-COF with an optical bandgap of 1.80 eV can be used as a visible light responsive photocatalyst, and the speed of hydrogen evolution by TP-COF could achieve up to 58.4 μmol g⁻¹h⁻¹ under visible light irradiation. The efficient photocatalysis performance could be attributed to the photogenerated charge separation and transport of TP-COF by the fluorescence resonance energy transfer (FRET) from tetraphenylethylene to porphyrin. The successful preparation of this type of COF according to the designed structure provides a new way to realize photocatalyst targeting synthesis for better photocatalysis.

基于四苯基乙烯和卟啉的方形晶格共价有机框架，用于有效的光催化析氢

设计了一种晶体双光电结构单元二维周期方阵共价有机框架，并以1,1,2,2-四(4-甲酰基-(1,1′-联苯))乙烯和5,10,15,20-四(4-氨基苯基)- 21h, 23h -卟啉为AA层结构，以希夫碱缩合为靶合成，命名为TP-COF。TP-COF具有良好的光电响应，结晶度好，比表面积高(1812 m2 g−1)。TP-COF的光学带隙为1.80 eV，可作为可见光响应光催化剂，在可见光照射下，TP-COF的析氢速度可达58.4 μmol g−1h−1。TP-COF的高效光催化性能可归因于其在光能下的电荷分离和从四苯基乙烯到卟啉的荧光共振能量转移(FRET)。根据设计的结构成功制备了这种类型的COF，为实现光催化剂靶向合成提供了一条新的途径，以获得更好的光催化效果。
