The main factors affecting the chirality and stability of PANI(+)-HCSA are moiety present, concentration, stereochemistry, chain length of the amino acids, time period for the doping, hydrogen bonding and so on. The corresponding CD spectra exhibited no measurable optical activity and consistent with complete de-doping of ES to EB. Further, on doping the solution, we have got the precipitate, which showed a remarkable optical activity. The CD spectra shows retention of the optical activity in solid phase obtained after de-doping of the solution.
