摘　　要：以咔唑为原料,经溴乙烷的烷基化、NBS的溴化,得到3,6-二溴-9-乙基咔唑3,然后与噻吩硼酸偶联和Vils-meier-Haack反应,得到一种新型咔唑衍生物5.化合物5是一种制备染料敏化太阳能电池中染料的重要中间体,经IR及NMR表征表明结构正确.3,6-Dibromo-9-ethyl-9H-carbazole 3 was prepared from carbazole via alkylation reaction with EtBr and bromonation reaction with NBS.Treatment of 3 with thiophen-2-ylboronic acid through Suzuki coupling reaction and with POCl3/DMF through Vilsmeier-Haack reaction gave dialdehyde 5,which is an important intermediate for preparation of organic dyes in dye-sensitized solar cells.The compound 5 is characterized by IR and NMR spectra.
