- Abstract
- We have developed a high performance fluorescent host material, 6-anthracene-9-yl-2,3-di-p-tolyl benzo[b]thiophene (ATB), for blue organic light-emitting diodes. ATB formed a stable amorphous solid state film with a high glass transition temperature (T-g=116 degrees C). The multilayer devices fabricated using ATB as a blue host material showed higher power efficiency (6.4 lm/W at 1000 cd/m(2)) than the conventional device using 2-tert-butyl-9,10-di(2-naphthyl)anthracene (TBADN) (4.3 lm/W at 1000 cd/m(2)). The half lifetime of the ATB device (6480 h at 1000 cd/m(2)) was also enhanced compared to the TBADN device (5341 h at 1000 cd/m(2)). (c) 2007 American Institute of Physics.
