Abstract

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,C4′)]acetylacetonate [(dfpypy)2Ir(acac)], we developed OLEDs that realized a low driving voltage of 3V and a high power efficiency (νp) of 32 lmW-1 at 100 cdm-2.
