Photomechanical Effect in Monolayers of Azo-benzene Side Chain Polymers

[Chem. Lett., pp.1739-1742, 1993]

Expansion ļ-ľ shrinkage behaviors of photoresponsive monolayers at the air/water interface are investigated using azobenzene side chain polymers. Influence of the spacer length implies that the photomechanical effect in the present systems is attributed to the reversible on/off contact of the azobenzene side unit with the water surface (Fig.1).
