Bipyridine-containing π-conjugated polymers bearing optically active amide groups: mechanistic aspects of formation of chiral higher-order structures

Abstract

π-Conjugated polymers with optically active substituents possibly form chiral higher-order structures. In the present study, novel bipyridine- and biphenyl-containing poly(phenyleneethynylene)s [poly(1-2) and poly(1-3)] were synthesized by the Sonogashira–Hagihara coupling polymerization...
