Summary
Optically active poly(2-methoxyaniline) (PMOA) was synthesized by electrochemical polymerization of 2-methoxyaniline in the presence of β-cyclodextrin sulfate (CDS). The synthesized PMOA films were characterized by induced circular dichroism (ICD) and UV-vis spectra. PMOA films showed a mirror-imaged ICD spectrum while they were respectively prepared at pH 3 and lower pH values, which suggested that opposite one-perfected helical handedness was induced into PMOA. Nevertheless, post-treatments, such as dedoping, redoping and thermo-treating, seemed no influence on helical handedness of PMOA.
