Yellow organic electroluminescent device based on novel thiophene Al complex as an emitting layer

A novel aluminum complex, Al(DTP) sub(3) (DTP identical with 1,3-di-(2-thienyl)-1,3-propanedione), was synthesized and applied to an organic electroluminescent (EL) device as an emitting material and an electron transporting material. The double layered EL device was fabricated by using triphenyldia...

Summary:A novel aluminum complex, Al(DTP) sub(3) (DTP identical with 1,3-di-(2-thienyl)-1,3-propanedione), was synthesized and applied to an organic electroluminescent (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) sub(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 Al(DTP) sub(3) with a maximum luminance of 400 cd/m super(2) at 17 V and 400 mA/cm super(2).
