A novel aluminum complex, Al(DTP)(3) (DTP = 1,3-di-(2-thienyl)-1,3-propanedione), was synthesized and applied to an organic eletroluminescent (EL) device as an emitting material and an electron transporting material. The double layered EL device was fabricated by using triphenyldiamine derivative (TPD) as a hole transporting layer and Al(DTP)(3) as an active emitting layer sandwiched between indium-tin oxide (ITO) and an alloy of Al/Li (99:1) electrodes. The deposited EL device was observed to emit a bright yellow light originating from AI(DTP)3 with a maximum luminance of 400 cd/m(2) at 17 V and 300 mA/cm(2).
