Preparation method and application of dye-based metal organic framework photocatalyst for inert C-H activation

The invention belongs to the technical field of photocatalytic materials, and relates to a preparation method and application of a dye-based metal organic framework photocatalyst for inert C-H activation. According to the preparation method, pyridylthioxanthone TXN is taken as a main ligand, 1, 3, 5-trimesic acid BTC is taken as an auxiliary ligand, Cu < 2 + > in metal copper salt is taken as a node, and the dye-based metal organic framework photocatalyst for inert C-H activation is prepared through a solvothermal method. According to the Cu-TXN-BTC prepared by the method disclosed by the invention, a novel functional dye pyridyl thioxanthone is adopted as a ligand, so that the Cu-TXN-BTC has stronger hydrogen atom capturing capability. Meanwhile, the auxiliary ligand increases the distance between thioxanthone dye parent nucleuses, and quenching of excited state energy of the dye parent nucleuses is avoided. The catalyst realizes synergism and coupling of two cyclic processes of photocatalysis and HAT, and r
