Abstract

The intercalation of inorganic materials into organized organic assemblies presents many opportunities for the development of new functional materials with superior physicochemical properties. We have designed a composite material comprising Prussian blue intercalated into photoresponsive organic molecules (azobenzene-containing multibilayer vesicles). Photoisomerization in the solid system was achieved by diluting the azobenzene-containing bilayer membrane in a poly(vinyl alcohol) matrix. The photoisomerization of the film was accompanied by a geometrically confined structural change within the vesicles, as reflected by changes in the dipole moment and electrostatic field. As a result, we were able to control the magnetic properties of this material by photoillumination.
