Abstract
'Formal' copolymers consisting of bithiophene and aromatic isothianaphthene units, based on 1,3-dithienylisothianaphthene (DTI) derivatives, have been synthesized. The obtained materials have low band gaps and show high intri nsic conductivities. The polymers are obtained after oxidative polymerizati on of the corresponding DTI monomers with FeCl3. Solubilizing alkyl and thi oalkyl side chains where introduced on different locations of the DTI skele ton. The substituents also influence the stability of the DTI monomers and the band gap of the polymers.
