Abstract

The invention discloses heteroaryl amine structure based organic compounds and applications thereof. The structure of the organic compounds simultaneously comprises different types of heteroaryl groups and amino groups. The organic compounds have a low LUMO energy level, a high glass transition temperature, and high molecular thermal stability, have low absorption and a high refractive index in the visible light range, and can effectively improve the light emission efficiency of an OLED device, after being applied to the CPL layer of the OLED device.

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...
