Synthesis and electroluminescent property of dinuclear aluminum 8-hydroxyquinoline complex

A new structural dinuclear aluminum 8-hydroxyquinoline complex (DAlq3) with two aluminum chelate-center was designed and synthesized. It was assessed as light-emitting material in organic light-emitting device (OLED). The green light emission was observed in films and OLEDs. DAlq3 has better electron mobility and also shows a higher electroluminescence (EL) efficiency than that of aluminum 8-hydroxyquinoline (Alq3).
