Abstract

The invention is applicable to the technical field of organic materials and provides an organic semiconductor material and a preparation method and application thereof. The organic semiconductor material provided by the invention has a structural formula as described in the specification.

Description

technical field [0001] The invention belongs to the technical field of organic materials, and in particular relates to an organic semiconductor material, its preparation method and application. Background technique [0002] With the development of the information age, organic electroluminescent flat panel displays (OLEDs) with high efficiency, energy saving and light weight and large-area white light illumination have attracted more and more attention. Organic electroluminescent devices must have a certain efficiency and lifespan in order to achieve full-color display and lighting applications. However, the luminous efficiency of the currently prepared organic electroluminescent devices is not high, which affects the market application of organic electroluminescent devices; [0003] At the same time, during OLED production and actual work, it will be affected by heat. The organic materials in the device are susceptible to these heat effects to induce the crystallization of ...
