Abstract

original image

Mimicking the texture and anisotropy of the template, birefringent conducting polymer films (see picture) have been obtained by electropolymerization of 3,4-ethyldioxythiophene (EDOT) within a hexagonal lyotropic liquid crystal. Using a self-assembled template to control molecular orientation in conducting polymers could enhance electronic and optical properties.
