摘要
以3-溴-9,9-二甲基芴为原料,通过Buchwald-Hartwig偶联反应合成了一种新化合物N,N′-二(联苯-4-基)-N,N′-二(9,9-二甲基芴-3-基)-9-苯基咔唑-2,7-二胺(2),其结构和性能经FL, UV-Vis,~1H NMR, GC-MS(EI),元素分析和TG-DSC表征。结果表明:2具有较好的热稳定性和较高的玻璃化温度,失重5%的温度为452℃,玻璃化温度为176℃;在425 nm波长激发下,2在445 nm处发出较强荧光(蓝光)。
A new compound N,N′-bis(biphenyl-4-yl)-N,N′-bis(9,9-dimethylfluoren-3-yl)-9-phenylcarbazole-2,7-diamine(2) was synthesized from 3-bromo-9,9-dimethylfluorene through Buchwald-Hartwig coupling reaction. The structure and performance of 2 were characterized by FL, UV-Vis, ~1H NMR, GC-MS(EI), elemental analysis and TG-DSC. The results showed that 2 had high thermal stability which 5% weight loss temperature was 452 ℃ and glass transition temperature was 176 ℃. 2 emitted strong fluorescence at 445 nm belongs at the PL excitation wavelength 425 nm.
