Abstract

We demonstrated that aqueous solutions containing a sulfonated polyaramide exhibited stir-induced chirality detected by circular dichroism (CD) spectroscopy. This phenomenon can be visualized as dynamics of supramolecular structure comprising hydrogen-bonded polyaramides. We further show that the sign of the CD response can be tuned using vortex direction, stirring-rate, and concentration.
