Abstract

A new triphenylamine-bridged fluoranthene derivative, 4-(7,10- diphenylfluoranthen-8-yl)-N-[4-(7,10-diphenylfluoranthen-8-yl)phenyl] -N-phenylaniline (BDPFPA), with a high glass transition temperature of 220 °C has been synthesized and characterized. BDPFPA is a highly fluorescent and versatile material that can be used as a nondoped green emitter and as a hole transporter. BDPFPA was used in a standard trilayer device as the emitting layer, which showed a low turn-on voltage (-1. The device also shows little efficiency roll-off at high brightness. For example, the efficiency can still be maintained at 11.4 cd A-1 (5.4 lm W-1) at a brightness of 10 000 cd m -2. These results are among the best reported for nondoped fluorescent green organic light-emitting diodes. A simple bilayer device, in which BDPFPA serves as a hole-transporting layer, has a maximum power efficiency of 3.3 lm W-1 and the performance is nearly 40 % higher than that of an N,N′-bis(1-naphthyl)-N,N′- diphenyl-1,1′-biphenyl-4, 4′-diamine (NPB)-based standard device.
