Abstract
A new three-dimensional (3D) metal-organic framework (MOF), [Zn 3L2(DMF)2]·2DMF (1-Zn), was prepared by the reaction of 5-(4-carboxybenzoylamino)-isophthalic acid (H3L) with Zn(NO3)2·6H2O under solvothermal conditions. Interestingly, the zinc ions in the zinc-carboxylate chains of complex 1-Zn could be exchanged with copper ions via direct single-crystal to single-crystal transformation (SC-SC). The complete and irreversible exchange of the metal ions from Zn2+ to Cu2+ and retention of the framework structure were verified by powder X-ray diffraction (PXRD), ICP-AES and SEM-EDS. Solid state photoluminescence measurements showed metal-specific properties.
