A New Family of Red Dopants Based on Chromene-Containing Compounds for Organic Electroluminescent Devices

摘要: 4-Dicyanomethylene-chromene moiety has been introduced as a π-electron acceptor in red fluorescent dye molecules for organic light-emitting devices (OLEDs). On the basis of this moiety, new family dopants with saturated emission, higher quantum yield, and convenient synthetic procedures have designed synthesized. Their photoluminescent electroluminescent properties examined compared. results, useful guidelines molecular design red-emission OLED applications are presented.
