文摘

The newly designed organic ligand 2-(p-bromophenyl)-1H-imidazole-4,5-dicarboxylic acid (p-BrPhH₃IDC) has been successfully prepared and its coordination features were explored. By the reactions of p-BrPhH₃IDC with main group or transition metals, six metal鈥搊rganic frameworks (MOFs), namely, [Ca(p-BrPhHIDC)(H₂O)₂]_n (1), [Sr(p-BrPhHIDC)(H₂O)]_n (2), [Zn(p-BrPhHIDC)(H₂O)]_n (3), {[Co(p-BrPhH₂IDC)₂]路2H₂O}_n (4), [Cd_1.5(p-BrPhHIDC)(p-BrPhH₂IDC)(H₂O)]_n (5), and {[Cd₂(p-BrPhHIDC)₂(4,4鈥?bipy)]路4H₂O}_n (4,4鈥?bipy = 4,4鈥?bipyridine) (6) have been synthesized under hydro(solvo)thermal conditions. X-ray single-crystal analyses reveal that they have rich structural chemistry ranging from one-dimensional (1D) (3), two-dimensional (2D) (1, 2, 4, and 5) to three-dimensional (3D) polymers (6). Furthermore, the existence of intermolecular hydrogen bonds and/or 蟺路路路蟺 stacking interactions between the aromatic groups supplies the additional stabilization for the solid-state supramolecular structures of polymers 3, 4, and 5. The solid-state photoluminescence properties of the polymers 1鈥?b>6 have been investigated as well.
