Abstract

Abstract: Covalent Organic Frameworks (COFs) have recently emerged as light‐harvesting devices, as well as elegant heterogeneous catalysts. The combination of these two properties into a dual catalyst has not yet been explored. We report a new photosensitive triazine‐based COF, decorated with single Ni sites to form a dual catalyst. This crystalline and highly porous catalyst shows excellent catalytic performance in the visible‐light‐driven catalytic sulfur–carbon cross‐coupling reaction. Incorporation of single transition metal sites in a photosensitive COF scaffold with two‐component synergistic catalyst in organic transformation is demonstrated for the first time. Abstract : A dual catalyst (Ace‐COF‐Ni), which is composed of a photosensitive covalent organic framework and single nickel sites, is reported. This dual catalyst exhibits excellent visible‐light and organometallic nickel synergistic catalytic performances for the sulfur–carbon cross‐coupling reaction.
