摘要：

A new spiro-type compound, 2-(10-biphenylanthracene)-spiro[fluorene-7,9'-benzofluorene] (BH-3B) containing anthracene moiety was prepared for the blue host material. Also new dopant materials, 2-[4'-(phenyl-4-vinylbenzeneamine)phenyl-spiro[fluorene-7, 9'-benzofluorene] (BH-3BD) and 4-[2 -naphthyl-4'(phenyl-4-vinylbenzeneamine)I pheny I (BD-1N) were successfully synthesized and a blue OLEDs were made from them. The structure of the device was as follows; ITO/DNTPD/alpha-NPD/Host:5% dopant/Alq3/Al-LiF. Among all of the devices, the device obtained from BH-3B host doped with 5% BH-3BD showed the best electroluminescence characteristics. The emission peak of EL is at 456 nm and the CIE value is (0.15,0.14). The brightness of the device is up to 5407 cd/m(2) at 10 V with the maximum EL efficiency of 3.4 cd/A. (C) 2008 Elsevier B.V.
