摘要：
New bipolar transport compounds containing a meta-conjugated phenothiazine/dimesitylborane hybrid have been synthesized and three of them were characterized via single crystal structural determination. The compounds exhibited emission from blue to green, and one of them has a dual emission behavior. Organic light-emitting diodes using the compounds as the host for the red-emitting guest, Ir(pq)(2)(acac) (bis(2-phenylquinoline)(acetylacetonate) iridium), have external quantum efficiencies in the range of 6.3-15.5%. Some devices have a negligible efficiency roll-off up to 1000 cd m(-2).
