Sun, Wenhao published the artcileDesigned polymeric conjugation motivates tunable activation of molecular oxygen in heterogeneous organic photosynthesis, Name: 2,2,6,6-Tetramethylpiperidin-4-one, the publication is Science Bulletin (2022), 67(1), 61-70, database is CAplus.
Herein, the first identification of tunable mol. oxygen activation induced by polymeric conjugation in nonmetallic conjugated microporous polymers (CMP) was reported. The conjugation between these can be achieved by the introduction of alkynyl groups. CMP-A with an alkynyl bridge facilitates the intramol. 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 (·O–2) and singlet oxygen (1O2), resp. This theory is substantiated by the different performances of these CMPs in the aerobic oxidation of sulfides and the dehydrogenative coupling of amines, and could provide insight into the rational design of CMPs for various heterogeneous organic photosynthesis.
