摘要
Photocatalysis has been emerging as a green and sustainable approach to chemical synthesis. Fabrication of an effective and robust photocatalyst to achieve efficient photocatalysis under mild conditions is of great significance but still challenging. Herein, taking the versatile typical Cu(I)-catalyzed clicked reaction, photoresponsive triphenylamine moieties were rationally incorporated into a triazole-linked porous organic polymer (POP), TATPA-POP, for application in a photocatalytic reaction. Analyses not only confirmed the successful construction of the triazole-linked POP but also showed its stability, nanosized porosity, and semiconductor features. Electron paramagnetic resonance (EPR) spectroscopy measurements revealed its ability to trigger the generation of reactive oxygen species (ROS) under light irradiation, making it have a high potential in ROS-involved photocatalytic reactions. The photocatalytic experiments in sulfide aerobic oxidations confirmed that the constructed POP is an effective and recyclable photocatalyst, demonstrating that, by utilizing the versatile click reaction to incorporate organic photochromic groups into POPs, highly effective heterogeneous photocatalysts can be facilely fabricated.
