Title:
ORGANIC ELECTROLUMINESCENT DEVICE CONTAINING TETRADENTATE PLATINUM (II) COMPLEX
Document Type and Number:
WIPO Patent Application WO/2019/128896
Kind Code:
A1
Abstract:
An organic electroluminescent device containing a tetradentate platinum (II) complex, comprising an anode, a cathode and an intermediate organic layer, wherein the intermediate organic layer at least comprises a light-emitting layer, and the light-emitting layer contains a tetradentate platinum (II) complex having the structure as shown in formula (3) as a phosphorescent doping material. Since the platinum (II) complex has a high fluorescence quantum efficiency, good heat stability and a low quenching constant, an OLED device, emitting orange light, having high light emission efficiency and low roll-off can be fabricated.
