Abstract

The copolymerization of 3-alkylthiophene and 3,4-dialkylthiophene units in well defined ratios leads to materials in which it is possible to modulate continuously the electronic properties such as the conjugation length and the energy-gap. The soluble materials have optical properties depending on the chemical composition of the chain. A macromolecular and optical characterisation has been performed on two copolymer series.
