Synthesis and Photoreduction Behavior of Novel Polymer Liquid Crystals Containing Viologen Units

Yongping Niu

Abstract

A series of novel polymer liquid crystal containing viologen units was synthesized and characterized. In the presence of excess 2-propanol, the photoreduction behavior of viologen polymers was investigated by using UV-visible spectra, the results showed that the photoreduction of these polyviologens followed the second-order reaction law, the calculated rate constants were related to their weight average molecular weights. The effect of 2-propanol was also observed.
