Abstract

We present a novel synthetic method for a chiral conjugated polymer represented by helical polyacetylene. The method is based on chiral nematic liquid crystal (LC) that is used as an asymmetric reaction field for acetylene polymerization. The chiral nematic LC is prepared by adding a small amount of chiral compound such as biaxially chiral binaphthyl derivative into nematic LC. The asymmetric reaction field is constructed by dissolving Ziegler-Natta catalyst into the chiral nematic LC. The interfacial acetylene polymerization under the asymmetric reaction field gives rise to helical polyacetylene with one-handed screwed fibril morphology. It should be emphasized that a method analogous to that using chiral nematic LC is also feasible for other kinds of helical aromatic conjugated homo- and co-polymers, which might allow us to disclose uncultivated fields of liquid crystal in polymer synthesis.
