In order to obtain crystalline photochromic materials combining the advantages of photochroms in liquid and polymeric solutions (high quantum yields) and in the solid state (enhanced resistance to photodegradation) a photochromic adduct consisting of a metal-organic framework [Zn4(dmf)(ur)2(ndc)4] (ndc2– is 2,6-naphthalenedicarboxylate, ur is urotropine, dmf is N,N-dimethylformamide) and 2,3-bis-(2,5- dimethylthiophen-3-yl-cyclopent-2-en-1-one) is synthesized (compound 1). The photochemistry of the adduct is studied. Solid 2,3-diarylcyclopentenone exhibits photochromism typical of diarylethenes. Quantum yields of the adduct photocoloration and photobleaching turn out to be 1.5 and 3 times higher respectively than those for solid compound 1 and lower than those of solution 1 in acetonitrile by an order of magnitude. The number of photochemical cycles for compound 1 in the solution, the solid state, and the adduct composition is limited by the monomolecular side reaction.
