摘要:	Tetrasubstituted-pyrenes containing peripheral diarylamines (1-4) or fluorenes (5-6) have been synthesized. These compounds are highly fluorescent and possess high morphological stability and thermal stability. Compounds containing peripheral arylamines (1-3) can be used as the hole-transport and green-emitting materials for two-layered electroluminescent devices. Compounds with peripheral fluorenes (5-6) are efficient blue emitters and exhibit ambipolar carrier-transport characteristics with high electron mobilities (10(-3)-10(-2) cm(2)/V s) and high hole mobilities (>10(-3) cm(2)/V s). Non-doped blue-emitting devices with promising electroluminescent performance (i.e., high efficiency and narrow/saturated emission) can be achieved using fluorene-substituted pyrenes as either the holetransport/emitting layer or the electron-transport/emitting layer in the two-layered devices.
