双取代咔唑化合物的合成及光谱性质研究

Synthesis and spectral study of disubstituted carbazole compounds

以咔唑为分子主体,选择了3种不同的共轭小分子修饰到咔唑分子上,合成了3种A-π-D-π-A型ICT化合物,研究了其光谱性能、考察了不同极性溶剂对光谱的影响,及可能的ICT过程.结果表明化合物a具有优良的电荷转移效果,有望应用于微环境极性探针及有机光电材料领域.

To synthesize three A-π-D-π-A ICT compounds, we employed carbazole as molecular subject and choose three kinds of conjugated molecules to modify carbazole molecule. The spectral properties, the effects of different solvents on the spectra of these compounds were investigated. The ICT processes of compounds were also studied. The results show that three compounds have excellent charge transfer effect, and the compound a have potential applications in the micro environment polarity probe and organic photoelectric material.
