摘要：

2,5-Dimethoxy-1,4-bis[2-(3,4,5-trimethoxyphenyl)ethenyl]benzene was synthesized using the Wittig reaction and the mixture of the three possible cis,trans-isomers was separated by preparative HPLC. The spectroscopy, conductivity and solubility of the isomers are presented. NMR measurements provided information about the molecular structure and dynamics of the separate isomers.
