Designed polymeric conjugation motivates tunable activation of molecular oxygen in heterogeneous organic photosynthesis
文献摘要：
Photocatalytic oxidative organic reactions are important synthetic transformations,and research on reac-tion selectivity by reactive oxygen species (ROS) is significant.To date,however,there has rarely been any focus on the directed generation of ROSs.Herein,we report the first identification of tunable molec-ular oxygen activation induced by polymeric conjugation in nonmetallic conjugated microporous poly-mers (CMP).The conjugation between these can be achieved by the introduction of alkynyl groups.CMP-A with an alkynyl bridge facilitates the intramolecular charge mobility while CMP-D,lacking an alkynyl group enhances the photoexcited carrier build-up on the surface from diffusion.These different processes dominate the directed ROS generation of the superoxide radical (·O2-) and singlet oxygen (1O2),respectively.This theory is substantiated by the different performances of these CMPs in the aerobic oxi-dation of sulfides and the dehydrogenative coupling of amines,and could provide insight into the rational design of CMPs for various heterogeneous organic photosynthesis.
