Synthesis and characterization of copolymers of 3-n-hexyl thiophene with 3-cyclohexyl thiophene

Abstract

Electrically conducting poly(thiophenes) functionalized with hexyl and cyclohexyl side chains have been synthesized. Poly[3-hexyl thiophene-co-3-cyclohexyl thiophene] with different hexyl and cyclohexyl contents were synthesized and characterized. The regioregularity of the copolymer was very much affected and the amount of miscouplings rose with the increase of cyclohexyl thiophene. These structural defects affect the optical, conducting and electrochemical properties of the copolymer.
