1A17 Formation mechanism of helical polyacetylene in chiral nematic liquid crystal

Abstract

Recently we synthesized helical polyacetylene under asymmetric reaction field that was prepared by adding a catalyst into chiral nematic liquid crystal (N^*-LC). The helical polyacetylene with vertically aligned fibril morphology was also synthesized by constructing the homeotropic chiral nematic LC field. In this study, we focused on the growing behavior of chiral nematic LC domains from isotropic phase in thermally cooling process through measurements of polarizing optical microscope, and then investigated the formation mechanism of spiral morphology of helical polyacetylene in chiral nematic LC field.
