摘要: Dibenzofuran (DBF) is converted to a vacuum-sublimable, electron-transporting host material via 2,8-substitution with diphenylphosphine oxide moieties. Close π−π stacking and the inductive influence of PO moieties impart favorable electron-transport properties without lowering triplet energy. A maximum external quantum efficiency 10.1% luminance power 25.9 lm/W are realized using this as for blue-green electrophosphorescent molecule, iridium(III) bis(4,6-(di-fluorophenyl)pyridinato-N,C2‘)picolinate (FIrpic).
