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

摘要

The present invention relates to an organic light-emitting material based on a platinum tetradentate ONCN complex, a preparation method and application thereof in organic light-emitting diodes, A platinum (II) tetradentate ONCN complex light-emitting material having the chemical structure of Formula I can be used for manufacturing organic light emitting diodes with pure greenemission. The material has been optimized in structure and has better anti-aggregation ability compared with the reported platinum (II) tetradentate ONCN complex light-emitting material. The emission spectrum of the material only slightly changes or even remains unchanged at high doping concentration, so the organic light-emitting diode made of this material obviously has higher emission efficiency. The preparation method for the complex light-emitting material is simple and does not require the use of highly toxic and harmful reagents, and is more suitable for industrial preparation systems.;
