| Abstract | Novel distyrylarylene-based blue host materials, 4,4-bis(1,2-diphenylvinyl)-p-terphenyl (2), 4,4'-bis[1-phenyl-2-(p-tolyl)vinyl]-p-terphenyl (3) and 4,4'-bis[1-phenyl-2-(4,4'-biphenyl)vinyl]-p-terphenyl (4) were successfully synthesized using 4,4'-bisbenzoyl-p-terphenyl (1) through Wittig-Hornor reaction and a blue organic light-emitting diode (OLED) was made from them. The structure of the blue device is ITO/DNTPD/NPB/Host:DSA-Ph/Alq(3)/Al-LiF. Here, NPB is used as a hole transport layer, DNTPD as the hole injection layer, DSA-Ph as the blue dopant, Alq(3) as the electron transport layer and Alq(3) as the cathode. The blue device doped with 5%-DSA-Ph shows a blue EL spectrum at 463 nm and a high efficiency of 4.14-5.13 cd/A. (c) 2007 Elsevier B.V. All rights reserved. |
