We report the synthesis of all-conjugated branched poly(thiophenes) with a control over the degree of nonlinearity via two different routes. In the first approach a branched monomer is polymerized using three different catalysts which differentiate in the degree of association to the π-system of the polymer backbone. In the second approach a copolymerization is performed with the branched and a linear monomer. In a next step the influence of the different degrees of nonlinearity on the optoelectronic properties is investigated by UV–vis and fluorescence spectroscopy. Finally, the thermal behavior, the morphology, and the electrical properties at the nanoscale of the material in solid state are studied using DSC and AFM techniques.
