| Abstract | Liquid crystal electro-polymerization Chiral conjugated polymers were prepared by electrochemical polymerization of achiral monomers in a chiral liquid crystal (CLC) electrolyte solution [1,2]. The polymer films prepared in liquid crystal shows electrochromism (Fig 1), and circular dichroism. This method can be called "liquid crystal chiral electrochemical polymerization". In this report, electrochemical polymerization of thiophene derivatives by using cholesteric liquid crystal electrolyte solution was performed. The surface morphology of the polymers was observed with scanning electron microscopy (SEM) polarizing optical microscopy (POM) observations. The polymers thus synthesized show so-called “optically active electrochromism”. Optical rotation degree of the film is comparable with Faraday rotation of inorganic materials. The ellipticity of this polymer is also found to exhibit hysteresis with redox cycle. The optical rotation and circular dichroism of the optically active polymer can be precisely controlled through electric field by electrochemical method. |
