  "abstract": "Single crystals of the ionic MOF {[Zn 2 (BDC) 2 (OAc)] -} 2 [Zn(DMSO) 6 ] 2+ have been grown and their photoluminescence recorded as excitation-emission maps.Solvated crystals in the mother liquor, dimethyl sulfoxide, and 1,2-dichloroethane exhibit broadband visible emission centred at approximately 440 nm under a narrow excitation band near 300 nm.The sharp excitation indicates excitation of the linker in a well-defined ground-state geometry rather than of a heterogeneous defect ensemble.The featureless visible envelope is attributed to subsequent structural relaxations on the excited-state potential-energy surface.The same motif is observed for optically clear and cloudy crystals, supporting the assignment of the emission as intrinsic to the framework rather than defect-centred.",
