  - '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.@eng'
