合成了一种含有B(Mes)2基团的新型吲哚[3,2- B]咔唑衍生物,5,11-二丁基-2,8-二(二烷基苯基)吲哚[3,2- B]咔唑(DBDMBICZ),并通过元素分析、核磁共振、质谱对其进行了结构表征。采用热重分析、电化学方法、紫外-可见光吸收光谱和荧光光谱对其进行了热、电化学和光物理性质的表征。DBDMBICZ在溶液中具有较高的荧光量子产率(Φmax=0.76),优异的热稳定性(Td=290℃,Tg=170℃)和电化学稳定性。以DBDMBICZ为发光层,制备了ITO/NPB/CBP/发光层/Bphen/ liff /Al结构的多层oled器件。该器件在不同电压下具有相同的纯蓝色发射,具有较好的电致发光性能。结果表明,DBDMBICZ作为一种优良的光电材料在光学领域具有潜在的应用前景。
A novel indolo[3,2-b]carbazole derivative containing B(Mes)2groups, 5,11-dibutyl-2,8-bis(dimesitylboryl) indolo[3,2-b]carbazole (DBDMBICZ), was synthesized and structurally characterized by elemental analysis, NMR, MS. The thermal, electrochemical and photophysical properties of DBDMBICZ were characterized by thermogravimetric analysis, electrochemical methods, UV–vis absorption spectroscopy and fluorescence spectroscopy. DBDMBICZ exhibited high fluorescence quantum yields (Φmax=0.76) in solution and excellent thermal stability (Td=290°C, Tg=170°C) and electrochemical stability. The multi-layered OLEDs devices with the configuration of ITO/NPB/CBP/light-emitting layer/Bphen/LiF/Al are fabricated by using DBDMBICZ as light-emitting layer. The devices show the same pure blue emissions at different voltages and relative good electroluminescent performances. The results indicate that DBDMBICZ has potential applications as an excellent optoelectronic material in optical field.
