In the present study, two new donor–acceptor–donor-type molecules were synthesized and the electro-optical
properties of the resulting monomers and their corresponding polymers were investigated. Thiophene was selected
as the donor unit and cycloheptyl- and cyclooctyl- substituted benzimidazoles were used as the acceptor units. The
synthesized monomers and their electrochemically obtained polymers were characterized using cyclic voltammetry and
UV-Vis spectrometry. The optical band gap values of the polymers were 1.62 eV and the polymer films changed color to
gray upon oxidation, while they were brick red in their neutral states.
