Description

Technical field [0001] The invention relates to the field of electroluminescent materials, in particular to a new aromatic amine compound and its preparation and application. Background technique [0002] The host materials in electroluminescent devices mainly include small molecule host materials and polymer host materials. Many high-efficiency electroluminescent devices have been prepared using small-molecule host materials doped with phosphorescent complexes as light-emitting layers. In recent years, the use of polymer host materials doped with various phosphorescent complex guests as the light-emitting layer to prepare electroluminescent devices has received more attention. Due to the rapid development of optoelectronic communication and multimedia fields in recent years, organic optoelectronic materials have become the core of modern society's information and electronic industries. [0003] Organic electroluminescence device (OLED) is a new type of flat display device. Compa...
