-1,4-bis[2-(3,4,5-trimethoxyphenyl)ethenyl]benzene was synthesized usi
ng the Wittig reaction and the mixture of the three possible cis,trans
-isomers was separated by preparative HPLC. The spectroscopy, conducti
vity and solubility of the isomers are presented. NMR measurements pro
vided information about the molecular structure and dynamics of the se
parate isomers.
