  Highly efficient phosphorescent organic light-emitting diodes using a homoleptic iridium(III) complex as a sky-blue dopant

  摘要：

  Homoleptic triscyclometalated iridium(III) complex Ir(dbi)(3) was used as a dopant for sky blue phosphorescent organic light-emitting diodes (PHOLEDs). Its photophysical, thermal, electrochemical properties as well as the device performances were investigated. Ir(dbi)(3) exhibited high quantum yield of 0.52 in solution at room temperature. A maximum current efficiency and external quantum efficiency (EQE) of 61.5 cd A (1) and 23.1% were obtained, which are the highest ever reported for blue homoleptic iridium complexes. High efficiencies of 53.5 cd A (1) and 20.1% EQE were achieved even at the luminance of 1000 cd m (2). (C) 2013 Elsevier B. V. All rights reserved.

  摘要：

  提供了包括带有二苯并融合的5元环取代基的配合物。特别地，该化合物可以是包括咪唑配合到二苯基取代配体的铱配合物。配体的二苯并融合的5元环部分可能会扭曲或最小限度地与其余的配体结构平面不一致。该化合物可以用于有机发光器件，特别是作为蓝色器件中的发射掺杂剂。包含该化合物的器件可以表现出优异的颜色并提高稳定性。

  Compounds including a ligand with a dibenzo-fused 5-membered ring substituent are provided. In particular, the compounds may be iridium complexes including imidazole coordinated to the dibenzo-substituted ligand. The dibenzo-fused 5-membered ring moiety of the ligand may be twisted or minimally twisted out of plane with respect to the rest of the ligand structure. The compound may be used in organic light emitting devices, particularly as emitting dopants in blue devices. Devices comprising the compounds may demonstrate improved stability while maintaining excellent color.
