  text: The effects of solution‐state dielectric and intermolecular interactions on
    the degree of charge separation provide a route to understanding the switching
    properties and concentration dependence of donor–acceptor Stenhouse adducts (DASAs).
    Through solvatochromic analysis of the open‐form DASA in conjunction with X‐ray
    diffraction and computational theory, we have analyzed the ionic character of
    a series of DASAs. First‐ and third‐generation architectures lead to a higher
    zwitterionic resonance contribution of the open form and a zwitterionic closed
    form, whereas the second‐generation architecture possesses a less charge‐separated
    open form and neutral closed form. This can be correlated with equilibrium control
    and photoswitching solvent compatibility. As a result of the high contribution
    of the zwitterionic resonance forms of first‐ and third‐generation DASAs, we were
    able to control their switching kinetics by means of ion concentration, whereas
    second‐generation DASAs were less affected. Importantly, these results show how
    the previously reported concentration dependence of DASAs is not universal, and
    that DASAs with a more hybrid structure in the open form can achieve photoswitching
    at high concentrations.
