ORGANIC LIGHT-EMITTING MATERIAL BASED ON PLATINUM TETRADENTATE ONCN COMPLEX, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF IN ORGANIC LIGHT-EMITTING DIODE

摘要

An organic light-emitting material based on a platinum tetradentate ONCN complex, a preparation method therefor and an application thereof in an organic light-emitting diode. A platinum tetradentate ONCN complex light-emitting material having the chemical structure of formula I can be prepared into the organic light-emitting diode capable of emitting pure green light. After structure optimization, the material has better anti-aggregation capability than the reported platinum (II) tetradentate ONCN complex light-emitting material. The emission spectrum of the material in at high-doping concentration only changes slightly or even remains unchanged. The organic light-emitting diode significantly has higher emission efficiency. The method for preparing the complex light-emitting material is simple and does not use high-toxic harmful reagent, and is more suitable for industrial preparation system.
