Syntheses, structural diversity, and selective luminescence sensing of three Co(II)/Cd(II) metal-organic frameworks composed of carboxylic acids and nitrogen-rich mixed ligands
By adopting mixed-ligand strategy, three Co(II)/Cd(II) metal-organic frameworks were prepared by hydrothermal reactions of Co(II)/Cd(II) acetate with 1,2-phenylenediacetic acid or 1,3-phenylenediacetic acid(1,2-H(2)phda/1,3-H(2)phda) combining with two imidazolyl/trazol/pyridyl-type tectons, namely, {[Co(1,2-phda)(bip)(H2O)(2)]center dot 0.25H(2)O}(n) (1), {[Cd-0.5(1,2-phda)(0.5)(bip)(0.5)(H2O)(0.5)]center dot 0.5H(2)O}(n) (2) and [Cd-2(1,3-phda)(2)(itmb)(2)](n) (3) (bip = 3,5-bis(1-imidazoly)pyridine and itmb = 1-(imidazo-1-ly)-4-(1,2,4-trazol-1-ylmethyl)benzene). The single-crystal X-ray diffraction analyses show that three compounds contain various metal(II)-carboxylate motifs, including carboxylate mononuclear (1), carboxylate chain (2), and carboxylate layer (3), which are further extended by two kinds of coligands to afford a vast diversity of the structures from 3-connected {6(3)}-hcb topology (1), (4,4) grids layer (2) to 6-connected {4(12 center dot)6(3)} pcu topology (3). Furthermore, the photoluminescences of both Cd(II) complexes exhibit highly selective sensing of Fe3+ ion through fluorescence quenching, and may be used as a potential Fe3+ sensor material.
