Triphenylamine and its derivatives (TPAs) are promising for the photocatalytic oxidative coupling of thiols to disulfides, but suffer from the easy polymerization and difficult separation. In this paper, by immobilizing the TPAs into MOF with photoredox inert Sr nodes, the photo-generated electrons were successfully controlled to transfer from the excited TPAs to O₂, and finally realize the heterogeneous catalytic oxidation of thiols to disulfides. More details are discussed in the article by Zhang et al. on page 1093—1099.
