摘要The present invention relates to a platinum (II) tetradentate ONNO complex luminescent material, a preparation method, and an application thereof in an organic light emitting diode. A platinum (II) tetradentate bipyridinol ONNO complex luminescent material having the chemical structure represented by formula I may be used to manufacture organic light-emitting diodes that emit pure red light. Since the phenol group at a left end is connected to benzofuran, the emission spectrum of the luminescent material is more red-shifted than that of a bipyridinol ONNO-Pt (II) complex without a benzofuran group; meanwhile, a B group is introduced on a phenol ring at a right end, which effectively increases the anti-aggregation performance of the platinum (II) complex; the self-quenching rate constant is low, the color purity of deep red light emission and good luminous efficiency may be maintained within a certain doping concentration range, and the material is more suitable for industrial preparation systems.
