The confinement of luminescent guest molecules in porous host materials can induce photophysical properties different from either component in isolation. In this work, we studied several host‐guest systems consisting of anthracene and its substituted analogs adsorbed in a series of metal‐organic frameworks (MOFs) and inorganic molecular sieves. Fluorescence photoswitching of the guest molecules through photoinduced dimerization is observed only in MOFs with a favorable pore volume and geometry.
