Highly Crystalline Ag‐based Coordination Polymers for Efficient Photocatalytic Oxidation of Sulfides

Abstract Coordination polymers (CPs) display great potential for the development of highly active photocatalysts. Herein, we report the fabrication of a highly crystalline CP, [Ag 2 BTT] n (BTT=benzene‐1,2,4,5‐tetrathiol). The crystal structure of [Ag 2 BTT] n was resolved and its performance for photocatalytic oxidation of thioanisole was explored. [Ag 2 BTT] n is highly active and selective for the photo‐oxidation of sulfides to sulfoxides under mild conditions, that is, in air, at room temperature and in the absence of a sacrificial reagent, co‐catalyst or redox mediator.
