DELAYED FLUORESCENCE MATERIAL AND ORGANIC LIGHT EMITTING DEVICE HAVING THE DELAYED FLUORESCENCE MATERIAL

摘要

A retardation fluorescent material is disclosed. The retarding fluorescent material has a molecular structure including an electron donor unit donating electrons and an electron acceptor unit coupled to the electron donor unit and accepting electrons, wherein the electron acceptor unit includes various electron And an indolocarbazole group including an acceptor unit. Such delayed fluorescent materials exhibit high structural and passive stability as well as high quantum efficiency.
