Intercalation of cation guests into a three-dimensional anionic host framework

A new three-dimensional photoluminescent host–guest open-framework, image (1) (dmp = 2,9-dimethyl-1,10-phenanthroline, bdc = 1,4-benzene-dicarboxylate), has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, IR spectrum, fluorescent spectrum, and thermogravimetric analyses. The structure of complex 1 features a three-dimensional supramolecular host architecture with photosensitizer-dye cation guests. Although Cu2+ was used as the starting material, no obvious signal was observed in ESR spectrum of 1, which indicates that all copper atoms in 1 are Cu+ and redox reaction occurred under the present hydrothermal condition.
