H-aggregation and Photo-responsive Behavior of Azobenzene Polyelectrolyte Containing DR-19
Recently, azo polymers have attracted considerable attention due to their potential uses in various optical applications 1-2. One of the most important and well-known properties of aromatic azo compounds is the photochemical trans-cis isomerization induced by UV or visible light 3-4. To fully understand the structure-property relationship, various types of azo polymers have been synthesized, and their photoresponsive behavior has been studied 5-8. An interesting class of synthetic surfactants involves photoresponsive amphiphiles, particularly those with azobenzene units in the tails. Tram-azobenzenes can be isomerized into their cis isomers by UV light with high yields (up to 80％ cis isomer) and without decomposition. The reverse isomerization can be realized either thermally or upon irradiation with visible light.
