Summary:Anthracene polymers containing flexible side chains were prepared and their photomechanical properties were investigated. The glass transition temperature of the polymers decreased and the photoreactivity at room temperature was enhanced with an increase of the flexible side chain content. When the polymer was formed into a fiber shape and illuminated with UV light, it bent toward the actinic light source. The deformation was investigated using a thermomechanical analyzer, which revealed that the polymers undergo fast expansion and slow contraction in response to UV light, due to the thermal expansion and photodimerization of the anthracene moiety, respectively.
