Abstract
Abstract Singlet oxygen ( 1 O 2 ) is ubiquitously involved in various photocatalytic oxidation reactions; however, efficient and selective production of 1 O 2 is still challenging. Herein, we reported the synthesis of nickel porphyrin‐based covalent organic frameworks (COFs) incorporating functional groups with different electron‐donating/‐withdrawing features on their pore walls. These functional groups established a dedicated outer‐sphere microenvironment surrounding the Ni catalytic center that tunes the activity of the COFs for 1 O 2 ‐mediated thioether oxidation. With the increase of the electron‐donating ability of functional groups, the modulated outer‐sphere microenvironment turns on the catalytic…
