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