Abstract

A new conjugated polymer combining in its structure thiophene rings and nitrogen containing heterocycles, poly[2,3-di(2-thienyl)quinoxaline], was synthesized by electrochemical methods using different experimental conditions. The monomer was electrochemically characterized. The morphology of the respective polymer was studied by SEM. The polymer shows low bandgap, dual p- and n-doping and good environmental stability. Theoretical calculations of global and local reactivity index such as frontier orbitals energy gap and Fukui functions present a good consistency with the experimental results.
