Synthesis, Crystal Structure and Fluorescence Emission Properties of Cd(II) and Pb(II) MOFs Based on Hydroxyethoxy Isophthalate Acid

Cadmium(1) and leadOP based three-dimensional metal-organic frameworks NMI's), namely ([Cd(L)(H2O)(2)]center dot " 1.5H(2)O}(n) (1) and [Pb(L)center dot H2O](n) (2), have been obtained through hydrothermal synthesis method using dimethyl 542hydroxyeiboxy) isophilialic acid (Me2L.) as a precursor and metal acetate. The crystal structures of two MOFs were revealed by single-crystal X-ray diffraction analysis and further confirmed by infrared spectrum (1K) and element analysis (EA). The XRD analysis of the MOFs ensured the single-crystal phase of the MOFs. The fluorescence emission property of two MOFs and H2L in the solid-state NV as investigated. Compared to the emission spectrum of Me2L, the (Juission maximum of compounds 1 and 2 all had red-shift but 2 shifted more stwere. CCDC: 1986790, 1; 1986793, 2.
