The current invention relates to novel platinum(II) based organometallic materials. These materials show high emission quantum efficiencies and low self-quenching constant. Also provided are high efficiency, green to orange emitting organic light-emitting diode (OLED) that are fabricated using platinum(II) based organometallic materials as the light-emitting material. The organometallic materials of the invention are soluble in common solvents; therefore, solution process methods such as spin coating and printing can be used for device fabrication. The devices fabricated from these materials show low efficiency roll-off.

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