中文摘要	two hybrids based on 1,8-disubstituted carbazole, 1,8-oxdcz and 1,8-mbicz, have been designed and synthesized through a facile process. the incorporation of oxadiazole or n-phenylbenzimidazole moieties at the 1,8-positions of carbazole greatly improves its morphological stability, giving glass transition temperatures (tg) as high as 138 and 154 degrees c, respectively. blue phosphorescent organic light-emitting devices (pholeds) with 1,8-mbicz exhibit almost the same performance as a similarly structured device based on the mcp host, and green pholeds employing the new host material 1,8-oxdcz exhibit an ideal turn-on voltage (2.5 v at 1.58 cdm-2), a maximum current efficiency (eta c,max) of 73.9 cda-1, and a power efficiency (eta p,max) of 89.7 lmw-1. these results are among the best performances of [ir(ppy)3]-based devices with simple device configurations.
