  text: Confinement within molecular cages can dramatically modify the physicochemical
    properties of the encapsulated guest molecules, but such host-guest complexes
    have mainly been studied in a static context. Combining confinement effects with
    fast guest exchange kinetics could pave the way toward stimuli-responsive supramolecular
    systems—and ultimately materials—whose desired properties could be tailored “on
    demand” rapidly and reversibly. Here, we demonstrate rapid guest exchange between
    inclusion complexes of an open-window coordination cage that can simultaneously
    accommodate two guest molecules. Working with two types of guests, anthracene
    derivatives and BODIPY dyes, we show that the former can substantially modify
    the optical properties of the latter upon noncovalent heterodimer formation. We
    also studied the light-induced covalent dimerization of encapsulated anthracenes
    and found large effects of confinement on reaction rates. By coupling the photodimerization
    with the rapid guest exchange, we developed a new way to modulate fluorescence
    using external irradiation.
