Abstract

The present invention relates to a platinum complex having an ONCN tetradentate ligand and containing carbazole, and the platinum complex has a structure as shown in a formula (I). The complex has bright green light emission wavelengths, and can be used in the field of OLED organic electroluminescent materials. By means of the structural design, the present invention can improve the heavy atomic effect of phosphorescent materials, enhance spin-spin coupling, and achieve high-efficiency conversion of T1-S0, thereby achieving high luminous efficiency. Moreover, a platinum complex molecule having an ONCN tetradentate ligand has simple synthetic steps and may modifiable sites. The steric hindrance added by the carbazole group contained can effectively reduce the aggregation effect between molecules, avoid the formation of an exciplex, and further improve the color purity and the luminous efficiency.
