  日期：2014.2

  An organometallic complex based on Be and pyridinepyrazole type ligand, bis(2-(1H-pyrazol-1-y1) pyridin-3-olate) beryllium (BePyPy), was synthesized as an electron transport type host material for blue phosphorescent organic light-emitting diodes. High triplet energy of 2.79 eV was obtained and the highest occupied molecular orbital/lowest unoccupied molecular orbital of BePyPy was -6.26 eV/-2.71 eV. The BePyPy host was effective as the host material for blue phosphorescent organic diodes and a high quantum efficiency of 19.7% was achieved. In addition, a mixed host device with the BePyPy host showed high quantum efficiency of 22.0% in the blue device. (C) 2013 Elsevier Ltd. All rights reserved.
