Abstract

The invention discloses an organic compound based on a heteroarylamine structure and its application. The structure of the compound of the invention contains different types of heteroaryl and amine structures at the same time, and has a shallower LUMO energy level, a higher Glass transition temperature and molecular thermal stability; low absorption in the visible light field and high refractive index, after being applied to the CPL layer of OLED devices, it can effectively improve the light extraction efficiency of OLED devices.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to an organic compound containing a heteroarylamine structure and its application in OLEDs. Background technique [0002] Currently, OLED display technology has been applied in smart phones, tablet computers and other fields, and will further expand to large-size applications such as TVs. However, due to the huge gap between the external quantum efficiency and internal quantum efficiency of OLEDs, the development of OLEDs is greatly restricted. Therefore, how to improve the light extraction efficiency of OLEDs has become a research hotspot. Total reflection will occur at the interface between the ITO film and the glass substrate and the interface between the glass substrate and the air, and the light emitted to the front of the OLED device to the external space accounts for about 20% of the total EL of the organic material film, and the remaining about 80% of the light It i...
