  A pyrene-phenanthroimidazole derivative for non-doped blue organic light-emitting devices

  摘要：

  We report a newly synthesized blue fluorescent pyrene-phenanthroimidazole based emitter Py-BPI and its applications in non-doped organic light-emitting devices (OLEDs). Py-BPI has a high fluorescence quantum yield of 40% and good thermal stability with a high glass transition temperature of 137 degrees C. Based on Py-BPI, OLEDs with several configurations have been fabricated. Among these devices, an OLED with only two organic layers of Py-BPI and BPhen demonstrates blue emission with high efficiencies of 3.93 cd/A and 3.2 lm/W and maintains a high efficiency of 3.83 cd/A even at a brightness of 5000 cd/m(2). Combining with its hole-transporting ability, Py-BPI is shown to be a versatile blue emitter especially suitable for high brightness applications. (C) 2013 Elsevier Ltd. All rights reserved.

  A series of phenanthroimidazole derivatives with N-1 and C-2 position modification have been synthesized, characterized and applied as non-doped emitters in organic light-emitting devices (OLEDs). The compounds show high fluorescence quantum yields high up to 87.51% in solid powder state as well as good thermal and film-forming properties. Crystal structures of 2N-PI, 1N-BPI and 2N-API were determined

  已合成，表征了一系列具有N-1和C-2位置修饰的菲并咪唑衍生物，并将其用作有机发光器件（OLED）中的非掺杂发射极。这些化合物在固态粉末状态下显示出高达87.51％的高荧光量子产率，以及良好的热和成膜性能。通过X射线晶体学测定2N-PI，1N-BPI和2N-API的晶体结构。研究了材料的光电性能，能级和分子结构之间的相关性。发现材料的荧光性质与二面角和部分置换位置有关。N-1-咪唑修饰（例如：2N-API）有利于深蓝色发射，尽管其量子产率相对较低，但显示出与C-2-咪唑衍生物相当的器件效率（例如：2N-BPI）。
