  A Dibenzofuran-Based Host Material for Blue Electrophosphorescence

  摘要：

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

  The present invention relates to a compound, a display panel and a display device. The compound has a structure represented by Formula I. The compound takes a spiro structure as a non-conjugated connecting unit, and a boron-containing group as an electron-accepting group. A light-emitting compound obtained by taking the group as a building block has a narrower half-peak width and higher color purity. The boron-containing spirt structure is connected with an electron-donating group to obtain a bipolar compound, and as a thermal activation delay fluorescence material, the bipolar compound can be used a light-emitting layer material, particularly a doped material, and can also be used as a fluorescent host material or a phosphorescent host material. The compound provided herein can achieve low drive voltages and high luminescence efficiencies when applied to organic electroluminescent devices.
