OLED (Organic Light Emission Diode) material, application and device

摘要: The invention relates to an OLED (Organic Light Emission Diode) material represented in the following formula (I) shown specification, and Ar1 is a triarylamine conjugated group. Pyrazine quinoxaline selected as parent, rigid carbon skeletons are all common plane, electron hole transport facilitated, performance of pyrazine improved due introduction alkynyl group cyano group; compound with good introduced into group, so that has both performance. Accordingly, higher performance, oxidation resistance vitrification temperature; amorphous films easy form; can be applied field used light emission layer and/or organic material.
