Mechanical properties of two amorphous azo polymers were characterized in tensile measurements and correlated with photoinduced behaviour of the materials observed upon irradiation with blue light of moderate intensity. Side-chain azobenzene poly(amide imide)s capable of forming high-quality free-standing layers of a large area and thickness of a few micrometers were chosen for the investigations...
We report on a series of photoresponsive azobenzene poly(ester imide)s thermally converted from their precursor poly(ester amic acid)s. Thermal properties as well as ability for efficient photoinduced chromophore orientation and polymer mass transport under linearly polarized blue irradiation were investigated, focusing on the effect of azo chromophore location within polymer chain. The amount of...
