  text: 'Photoisomerization of molecules dissolved in a polymer film can modulate
    its properties. In a previous paper (Mostafavi, S. H.; Macromolecules 2018, 51,
    2388−2394), it was found that the ultraviolet light-induced photoisomerization
    of spiropyran dopants could substantially increase adhesion to a glass surface.
    In this work, a different photochromic reaction, the visible-light-induced cyclization
    of a donor–acceptor Stenhouse adduct (DASA), leads to the opposite effect: the
    deadhesion of a polystyrene film from a clean glass surface. Measurements of the
    shear and pull-off adhesion strengths before and after visible irradiation show
    a light-induced decrease of 20–30%. The time required for delamination in water
    shows an even more dramatic decrease of 90%. Changes in the water contact angle
    and other measurements suggest that molecular-level noncovalent interactions between
    the polymer and glass are weakened after photoisomerization, possibly due to the
    molecular contraction of the DASA that disrupts the interaction between its amine
    groups and the surface silanols. The ability to reduce polymer adhesion using
    visible light enables the controlled release of dye molecules from a glass container,
    where these have been stored as a dry powder, into an aqueous solution. Embedding
    photochromic molecules in a polymer can lead to new effects that may have practical
    applications in stimuli-responsive materials.'
