  text: We investigate the influence of the host matrix on the photothermally driven
    actuation performance of negatively photochromic, donor−acceptor Stenhouse adduct
    (DASA)-based polymers. Using a modular Diels−Alder “click” platform, we designed
    polymeric materials with varying DASA incorporation and investigated the relationships
    between the material composition and the resulting physical, mechanical, and photoswitching
    properties. We demonstrate that increasing the DASA concentration in polymer conjugates
    has a dramatic effect on the material’s physical and mechanical properties, such
    as the glass transition temperature (Tg) and elastic modulus, as well as the photoswitching
    properties, which are found to be highly dependent on Tg. We establish using a
    simple photoresponsive bilayer that actuation performance is controlled by the
    bilayer stiffness rather than the photochrome incorporation of DASA. Finally,
    we report and compare the light-induced property changes in Tg and the elastic
    modulus between the materials comprising the open or closed forms of DASAs. Our
    results demonstrate the importance of designing a material that is stiff enough
    to provide the mechanical strength required for actuation under load, but soft
    enough to reversibly switch at the operational temperature and provide key considerations
    for the development of application-geared photoswitchable materials.
