摘要

We report on efficient blue organic light-emitting devices with an emission layer featuring a quasi-molecular quantum dot nanostructure as a charge carrier confining barrier, which was formed by doping a wide band gap molecule, 2-(2-hydroxyphenylbenzoxazole) lithium, into a newly synthesized blue host molecule, 9,10-bis-[4-(2,2-diphenylvinyl)-phenyl]-anthracene. The charge carrier confinement was greatly improved by doping with 10 percent wide band gap molecules, that led to a theoretical molecular quantum dot distance of 33 A. The device showed enhanced efficiency (approx 5 cd A~(-1)) and good colour purity (x = 0.16, y = 0.15), while the projected device lifetime reached approximately 20000 hat 150 cd m~(-2).
