摘要：

A high-efficiency, undoped, blue, organic light-emitting device was devised that employed a novel electroluminescent material 4-(7,10-diphenylfluoranthen-8-yl)-N,N-diphenylbenzenamine as electrofluorescence emitter. The device with a simple structure of ITO/N,N'-bis(1-naphthyl)-N,N'-diphenyl-1,1'-biphenyl-4,4'diamine/4-(7,10-diphenylfluoranthen-8-yl)-N,N-diphenylbenzenamine/4,7-diphenyl-1,10-phenanthroline/LiF/Al exhibited stable blue light emission of CIE chromaticity coordinates (x = 0.19 +/- 0.01 and y = 0.45 +/- 0.02), and a current efficiency of 6.0 cd A(-1) and a power efficiency of 4.6 Im W(-1).
