Abstract Three new terthiophene acrylic acids derivatives, 3-(4-([2,2':5',2''-terthiophen]-3'-yl)phenyl)acrylic acid (TTPAA), 3-(5'-(thiophen-2-yl)-[2,2':3',2''-terthiophen]-5''-yl)acrylic acid (TTTAA) and 3-(5-([2,2':5',2''-terthiophen]-3'-yl)furan-2-yl)acrylic acid (TTFAA) were synthesized and confirmed by FT-IR, 1H and 13C NMR, mass spectroscopy.These monomers were synthesized by hydroboration, suzuki coupling reaction, and knoevenagel condensation reaction. UV–visible absorption and PL emission bands of each monomers were observed TTPAA (UV-Vis: 310 nm, PL: 529 nm), TTPAA (UV-Vis: 337 nm, PL: 535 nm), and TTFAA (UV-Vis: 337 nm, PL: 508 nm), respectively. These molecules frontier orbitals showed that acrylic acids functional groups played a role as electron acceptor in terthiophene derivatives. Finally, electrochemically generated conducting polymers were studied by cyclic voltammetry, in-situ UV-Vis spectroscopy, and AFM techniques. Spectroelectrochemical experiments were performed to observe the absorption bands change of new polymers and analyzed by DCVA techniques.
