EMISSIVE COMPOUNDS FOR LIGHT EMITTING DEVICES

摘要

Disclosed herein are compounds represented by Formula (1), wherein R2 is an cyano, aryl and/or heteroaryl which can be from an optionally substituted phenyl, optionally substituted pyridinyl and optionally substituted pyrimidinyl; and wherein, R3 is a heteroaryl which can be from an optionally substituted carbazolyl, an optionally substituted benzocarbazolyl, an optionally substituted phenoxazolyl, an optionally substituted phenothiazenyl and an optionally substituted phenazinyl. Other embodiments provide an organic light-emitting diode device comprising a compound of Formula (1).
