A novel europium complex, Eu(MDFP)3(phen) (MDFP = 5-methyl-1,3-di-(2-furyl)-1,3-propanedione, phen = 1,10-phenanthroline), was synthesized and applied to an organic electroluminescent (EL) device as an emitting material and an electron-transporting material. The double-layered EL device has been fabricated by using triphenyldiamine derivative (TPD) as a hole-transporting layer and Eu(MDFP)3(phen 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 red light originating from Eu(MDFP)3(phen) with a maximum luminance of 32.0 cd/m2 at 9 V and 25.7 mA/cm2.
