摘要：

Structure, surface properties and morphology of a regioirregular conjugated poly(3-thiophene acetic acid) (PTAA) and four polyelectrolytes based on PTAA with various cations were studied by using FT-IR, H-1-NMR spectroscopy and SEM. The properties of PTAA and its polyelectrolytes depend on the unique combination of a hydrophobic backbone and hydrophilic ionic side groups. The thermal stability, fluorescence and conductivity properties were investigated. These polymers exhibited fluorescence emissions at about 565 nm characterized for the pi-conjugated polythiophene. Undoped polymers have a better conductivity than previous polymers.
