Abstract

A study was conducted to investigate selective chiral handedness induced in spin-coated polyaramide films. The possibility of a selective induction of optical possibility of a selective induction of optical was investigated using an artificial polymer system. The sulfonated polyaramide (PPSA) used in the study was synthesized by polycondensation between 2-sulfoterephthalic acid and 1, 4-phenylenediamine. It was observed that PPSA was dissolved in water despite a rigid structure composed of mainchain due to the presence of hydrophilic inverted sulfonic acid. Circular dichromism (CD) spectroscopy was used to probe the degree of optical activity of the spin-coated films and their handedness. The relationship between the films' optical activity and their molecular alignment was also investigated using ultraviolet-visible spectroscopy and polarizing optical microscopy.
