摘 要: 以咔唑为原料,经溴化、烷基化和Suzuki偶联等反应合成了4种9-烷基-1,3,6,8-四(α-噻吩)咔唑衍生物.利用核磁共振(氢谱和碳谱)、质谱及元素分析方法表征其结构,通过紫外-可见吸收光谱、荧光发射光谱、差热分析、热重分析和循环伏安法测定其发光特性、热学性能、最高占有轨道能和最低空轨道能.研究显示,新化合物分子可用于蓝色发光和空穴传输材料. Four of 9-alkyl-1,3,6,8-tetra(α-thienyl) carbazole1 derivatives were synthesized,and their structures were confirmed by 1HNMR,13CNMR,MS and elemental analysis.The luminescence characteristic,thermal properties,the highest occupied molecular orbital(HOMO) and the lowest unoccupied molecular orbital(LUMO) were studied by UV-Vis absorption spectra,fluorescence spectra,differential scanning calorimetry(DSC),thermogravimetric analysis(TGA) and cyclic voltammetry.The results show that the new compounds can be used for blue light emitting and hole transporting materials.
