AbstractNovel electron-acceptor materials based on poly(thienylene ethynylene) derivatives (PTE-BT and PTE-DCNTB) were synthesized and characterized by FTIR spectroscopy. Their thermal, electrochemical and optical properties were investigated. The π-conjugated polymers are soluble in common organic solvents. The maximum UV-Vis absorptions of PTE-BT and PTE-DCNTB in solution are observed at 460 and 390 nm, respectively. The electrochemical band gap was found to be 1.89 eV for PTE-BT and 2.01 eV for PTE-DCNTB. Both polymers are promising as electron-acceptor materials for photovoltaic applications.
