Abstract: A wide-energy-gap exciplex comprising bis[4-(9,9- dimethyl-9,10-dihydroacridine)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,C4')]acetylacetonate [(dfpypy)2Ir(acac)], we developed OLEDs that realize a low driving voltage of 3 V and a high power efficiency (ηp) of 32 lm W−1 at 100 cd m−2.
