Abstract Helical polyacetylene was synthesized under asymmetric reaction field constructed with chiral nematic liquid crystal (LC). The chiral nematic LC was prepared by adding a chiral phenylcyclohexyl (PCH) derivative, (R)- or (S)-PCH308*, as a dopant, into an equi-weighted mixture of two kinds of nematic LCs. Acetylene polymerization was carried out with Ti(O-n-Bu)4 - Et3Al catalyst dissolved in the chiral nematic LC. It is found from SEM measurements that the polyacetylene films is composed… CONTINUE READING
