Abstract: Molecular crystal engineering, i.e. the design and synthesis of solid state molecular materials with predefined properties, is used here to exploit non-covalent interactions to pre-arrange buiding blocks in their crystalline state for properties modification and specific applications, all involving the absorption of UV radiation. Examples and problems will be presented; among them: (i) single crystal to single crystal photodimerization of cinnamic acid derivatives and the effect of crystal size on the solid-state reactivity; (ii) co-crystallization as a tool to switch from fluorescence to phosphorescence in the solid state; (iii) molecular crystals for dye-sensitized solar cells applications.
