  text: Photoisomerization and photoluminescence are two distinct energy dissipation
    pathways in light-driven molecular motors. The photoisomerization properties of
    discrete molecular motors have been well established in solution, but their photoluminescent
    properties have been rarely reported—especially in aggregates. Here, it is shown
    that an overcrowded alkene-based molecular motor exhibits distinct dynamic properties
    in solution and aggregate states, for example, gel and solid states. Despite the
    poor emissive properties of molecular motors in solution, a bright emission is
    observed in the aggregate states, including in gel and the crystalline solid.
    The emission wavelength is highly dependent on the nature of the supramolecular
    packing and order in the aggregates. As a result, the fluorescent color can be
    readily tuned reversibly via mechanical grinding and vapor fuming, which provides
    a new platform for developing multi-stimuli functional materials.
