摘要：
Awide-energy-gap exciplex comprising bis[4-(9,9-dimethyl-9,10-dihydroacridine-10-yl)phenyl]diphenylsilane (SiDMAC) and 9,9-bis[4-(phenylsulfonyl)phenyl]fluorene (BPSPF) was developed as a host material for blue phosphorescent organic light-emitting devices (OLEDs). Using a combination of this exciplex as a host material and blue phosphorescent emitter iridium(III) bis[(2',6'-difluoro-2,3'-bipyridinato-N,C-4')]acetylacetonate [(dfpypy)(2)Ir(acac)], we developed OLEDs that realized a low driving voltage of 3 V and a high power efficiency (eta(p)) of 32lm W-1 at 100 cd m(-2).
