摘　　要：以过渡金属催化的C—C键偶合反应为关键步骤,设计合成了带4条烷基侧链的锯齿形六联寡聚噻吩波拉化合物I,采用~1H NMR、^(13)C NMR和元素分析等测试手段确证了化合物I的结构.采用POM,DSC,TEM,UV-Vis,PL,CV等测试手段对化合物I的性质进行了研究,该化合物能组装形成单向液晶柱相,在溶液中能组装形成具有三维网络状结构的凝胶,具有较大的Stokes位移,是潜在的荧光标记及半导体材料.Sexithiophene based bolaamphiphile I with four lateral alkyl chains was synthesized by transition-metal catalysized Kumada and Suzuki coupling reactions as key steps.The structure of compound I was identifiedwith 1H NMR,13C NMR and elemental analysis.The properties of the compound I were investigated with POM,DSC ,TEM, UV-Vis, PL and CV.The results showed that compound I could self assemble into a monotropic co-lumnar phase in its pure state and gels with three-dimensional network structure in the solution.PL measurementshowed that I had a large Stokes shift, indicating that I was a potential candidate as fluorescent label materialsand semiconductor materials.
