两种新型咔唑衍生物的合成及其光电性能

Synthesis of Two Novel Carbazole Derivatives and Their Optoelectronic Properties

以咔唑、三苯基氯硅烷及2-溴芴为原料,经甲基化、硼酸化、Ullmann偶联、Suzuki偶联等反应合成了两种新型咔唑衍生物——3,6-二(9,9-二甲基-9H-2-芴基)-9-苯基-9H-咔唑(1a)和3,6-二[(4-三苯硅基)苯基]-9-苯基-9H-咔唑(1b),其结构经1HNMR和元素分析表征。用UV-Vis,荧光光谱和循环伏安曲线研究了1a和1b的光电性能。

Two novel carbazol derivatives,3,6-bis（9,9-dimethyl-9H-fluoren-2-yl）-9-phenyl-9H-carbazole（1a） and 3,6-bis[（4-triphenylsilanyl）phenyl]-9-phenyl-9H-carbazole（1b）,were synthesized through methylation,Ullmann reaction,boric acidification and Suzuki coupling reaction using carbazole,triphenylsiyl chloride and 2-bromo-9H-fluorene as the starting materials.The structures were characterized by 1H NMR and elemental analysis.The optoelectronic properties of 1a and 1b were investigated by UV-Vis spectra,fluorescence emission spectra and cyclic voltammetry.
