Three fluorescent coordination polymers (CPs) including [Zn(ppvppa)(5-NO 2 -1,3-BDC)(H 2 O)] ( 1), [Cd-(ppvppa) Compound 1 has a onedimensional (1D) double-stranded chain structure. 2 and 3 have different two-dimensional (2D) grid-like networks formed by either bridging 1D [Cd(ppvppa) 2 ] n chains with 2,5-FDC ligands or linking 1D [Ni 2 (ppvppa) 2 ] n chains with 5-NO 2 -1,3-BDC ligands. The ligand ppvppa and the three CPs could detect Cr 2 O 7 2− and CrO 4 2− in aqueous solutions by selective fluorescence quenching. The detection limit of the most responsive complex 3 was 1.39 ppb for Cr 2 O 7 2− (pH = 4) or 0.09 ppb for CrO 4 2− (pH = 12), which are below the allowable limits set by the United States Environmental Protection Agency and European Union and the lowest among the known CPs-based sensors. The mechanism of such an emission quenching process may be ascribed to the overlap between the absorption band of the analyte and those of the excitation and emission bands of 3.

“…These exploits have also been crucial towards the development of Ag I coordination polymers with structural interest and potential applications, which include luminescence [26][27][28] , anion exchange [28][29][30] , antibacterial [31][32][33][34][35][36][37] and catalytic activity. [38][39][40][41][42][43][44] Focusing on the latter, several Ag CPs and MOFs have been especially used as catalysts in organic transformations that involve alkyne activation 45,46 due to the supreme capability of the metal to form organometallic intermediates through π-coordination with the carbon-carbon triple bond.…”

In this work we study the coordination chemistry of a series of semi-rigid benzotriazole based ligands (L 1-L 3) along with the low coordination number but versatile Ag I ions. This has led to nine new coordination compounds formulated [Ag(L 1)(CF3CO2)] (1), [Ag2(L 1T)2(CF3SO3)2]•2Me2CO (2), [Ag(L 2T)(ClO4)(Me2CO)] (3), [Ag(L 2T)(BF4)(Et2O)] (4), [Ag2(L 3T)2(ClO4)2]2 (5), [Ag(L 3)(NO3)] (6), [Ag2(L 3T)2(CF3CO2)2] (7), [Ag2(L 3T)(CF3SO3)2] (8) and [Ag2(L 3T)2(CF3CF2CO2)2]•2Me2CO (9). These compounds show structural diversity including dimers (5, 7, 9), one dimensional (1D) (3, 4, 6) and two dimensional (2D) (1, 2, 8) coordination polymers. The presence of the two-CH2-units between the three rigid backbones, benzotriazole/-C6H4-/benzotriazole, provides a limited, but significant, flexibility in L 1-L 3 , influencing their variety coordination abilities. Interestingly, certain structures exhibit an isomerism effect (L 1T-L 3T) in the benzotriazole unit when in solid state; a series of studies are indicative of the 1,1-form is generally dominant in solution even in cases where the crystal structure does not contain this tautomer. The homogeneous catalytic efficacy of all compounds against the well-known multi component A 3 coupling reaction and the hydration of alkynes were investigated. Compound 4 was identified as the optimal catalyst for both reactions, promoting the multicomponent coupling as well as the alkyne hydration reaction under low loadings (0.5 and 3 mol%, respectively) and in high yields (up to 99 and 93% in each case).

“…[1][2][3][4][5][6] The self-assembly of transition metal salts with mixed ligands of O-donor polycarboxylates and N-heterocyclic bridging ligands have been employed to construct MOCCs with diverse structures and properties. [7][8][9][10] In the self-assembling process, the connectivity and coordination modes of organic ligands usually govern the final coordination frameworks. [11][12][13] Even small structural changes of the organic bridging ligands such as the symmetry, length, flexibility or functional groups can lead to obvious differences in the ultimate framework structures and topological networks.…”

Three new cadmium(II) coordination compounds [Cd 2 (L) 2 (btec)(H 2 O) 2 ]•3H 2 O (1), [Cd(HL)(btb)] (2) and [Cd(L)(pda)] • 2H 2 O (3) were prepared by hydrothermal reactions of cadmium(II) chloride with ligands L (L = N,N-bis(3-pyridyl)octandiamide) in the presence of different aromatic polycarboxylates (H 4 btec = 1,2,4,5-benzenetetracarboxylic acid, H 3 btb = 1,3,5-tri(4-carboxylphenyl)benzene, H 2 pda = 1,4-phenylenediacetic acid). The structures of compounds 1-3 have been determined by X-ray single crystal diffraction analyses and further characterized by infrared spectroscopy (IR), powder X-ray diffraction (PXRD) and thermogravimetric (TG) analyses. Compound 1 displays a 3D metal-organic framework with (4,4,4)connected {6 2 .8 4 }{6 3 .8 3 }{6 4 .8 2 } topology constructed from 2D [Cd 2 (btec)] n layers and μ 2-bridging L ligands. Compound 2 is a 3D (3,3)-connected {10 3 } topological network based on the 3D [Cd(btb)] n− n framework and the protonated monodentate HL ligand. Compound 3 shows a 2D layer with (3,5)-connected (4 2 • 6 7 • 8)(4 2 • 6) topological structure, which are further linked by hydrogen bonding interactions to form a 3D supramolecular network. The influences of three aromatic polycarboxylates on the structures of title compounds are investigated. Further, the fluorescent properties of three cadmium(II) compounds and their fluorescent sensing properties towards small solvent molecules and metal cations have been studied.
