Abstract

The invention provides a compound and application thereof, wherein the compound has a structure as shown in a formula 1-1. When the compound is used in an organic electroluminescent device, especially as an electron injection / transmission material, the excitation voltage of the device can be effectively reduced, the luminous efficiency of the device can be improved, and the optimal effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of organic electroluminescence, in particular to an organic compound and its application, and also relates to an organic electroluminescence device. Background technique [0002] In recent years, organic light-emitting diodes (OLEDs) have developed very rapidly and occupy a place in the field of information display. This is mainly due to the fact that OLED devices can use high-saturation red, green and blue primary colors to prepare full-color display devices without additional backlight sources. It can achieve colorful, light and soft performance. Examples of such organic optoelectronic devices include organic light emitting diodes (OLEDs), organic field effect transistors, organic photovoltaic cells, organic sensors, and the like. The core of an OLED device is a thin film structure containing a variety of organic functional materials. Common functional organic materials include: hole injection materials,...
