Thermotropic and Solution Photoisomerization Properties of Side-Chain Liquid Crystalline Polymers Containing Methyl-Substituted Azobenzene Mesogens

The thermotropic and solution photoisomerization properties of a class of polyacrylates containing differently methyl-substituted azobenzene groups are presented.Methyl-substitution inhibits the tendency to crystallize and causes a dramatic decrease in the stability of the established nematic phases.These effects result from a restriction of the packing capability of the mesogenic groups and a reduction of their length-to-breadth ratio.In dilute solution all polymeric samples undergo trans-to-cis photoisomerization of the azo group upon irradiation in the absorption region of the ? ---> ?* electronic transitions.Photoisomerization rate constans are very similar and of the same order of magnitude as those observed for other polymeric systems containing the unsubstituted azobenzene chromophore.
