Abstract
The invention relates to a platinum (ii) tetradentate onno complex luminescent material, preparation method and application thereof in organic light emitting diode. A platinum (II) tetradentate pyridine diphenol ONNO complex light-emitting material having the chemical structure of Formula (I) can be used for manufacturing organic light-emitting diodes emitting pure red light. The light-emitting material of the invention, because the end of the left side thereof is connected to benzofuran, has more red shift than the emission spectrum of the bipyridyl phenol ONNO-Pt(II) complex without a benzofuran group, and the anti-aggregation performance of the platinum(II) complex is effectively increased, as a B group is introduced on the phenolic ring on the right side thereof, so the self-quenching rate constant is low, and the color purity emitting deep red light and better luminous efficiency can be maintained in a certain range of doping concentration, which is more suitable for industrial preparation systems.
