摘　　要：Covalent organic frameworks(coFs)driven photocatalytic organic transformations especially photooxidation reactions have become a fertile topic and attracted numerous research attentions.Boosting the charge generation and transport process is the key factor for achieving high catalytic efficiencies.As one of the most effective strategies,the introduction of"heavy atoms"into the long-range ordered conjugated backbones can effectively facilitate the intersystem crossing(isc)process and hence improve the generation of active oxygens,which is beneficial for the oxidation.In this work,we designed and synthesized a benzoselenadiazole based covalent organic framework(COF)material,BSe-COF with heavy atom of selenium(Se),and a benzothiadiazole based BT-COF with isomorphic backbone for comparison.
