One-Dimensional Coordination Polymers: Complexity and Diversity in Structures, Properties, and Applications

Thiolate-protected metal nanoclusters (or thiolated metal NCs) have recently emerged as a promising class of functional materials because of their well-defined molecular structures and intriguing molecular-like properties. Recent developments in the NC field have aimed at exploring metal NCs as novel luminescent materials in the biomedical field because of their inherent biocompatibility and good photoluminescence (PL) properties. From the fundamental perspective, recent advances in the field have also aimed at addressing the fundamental aspects of PL properties of metal NCs, shedding some light on developing efficient strategies to prepare highly luminescent metal NCs. In this Perspective, we discuss the physical chemistry of a recently discovered aggregation-induced emission (AIE) phenomenon and show the significance of AIE in understanding the PL properties of thiolated metal NCs. We then explore the unique physicochemical properties of thiolated metal NCs with AIE characteristics and highlight some re...

Luminescent one-dimensional nanoscale materials with PtII...PtII interactions.

The coordination chemistry of inorganic cobalt salt and the organic ligands H4bbh (=benzene-1,2,4,5-bihydrazide) and H3bcbh (=benzene-4-carboxylate-1,2-bihydrazide) generated through the in situ hydrothermal acylate reaction of H4bta (=benzene-1,2,4,5-tetracarboxylic acid) and H3btc (=benzene-1,2,4-tricarboxylic acid) with hydrazine hydrate, respectively, has been investigated. Three new coordination polymers were prepared and fully characterized by infrared spectroscopy, elemental analysis, and single-crystal X-ray diffraction. The compound [Co(μ3-H2bbh)(phen)]n (1) (triclinic space group P1 with a = 9.762(4) A, b = 10.169(4) A, c = 11.143(4) A, α = 80.96(3)°, β = 64.49(3)°, γ = 71.88(3)°, Z = 2) was synthesized from the reaction of CoCl2·6H2O, H4bta (=benzene-1,2,4,5-tetracarboxylic acid), N2H4·H2O, phen (=1,10-phenanthroline) and H2O, and consists of one-dimensional double-chains. [Co(μ4-H2bbh)(H2O)2]n (2) (monoclinic space group P2(1)/c with a = 6.8687(5) A, b = 7.5943(6) A, c = 10.0401(6) A, β = 95....

A new route for preparing coordination polymers from hydrothermal reactions involving in situ ligand synthesis.

The hydrothermal reaction of V2O5, H2C2O4·2H2O, en, KOH and NiCl2·6H2O gives a new two-dimensional open-framework solid; the extended structure consists of a two-dimensional network formed by the interconnection of each [V18O42Cl] cage to four other neighboring units via six [Ni(en)2]2+ bridging groups.

A two-dimensional framework of novel vanadium clusters bridged by [Ni(en)2]2+: K{V12IVV6VO42Cl[Ni(en)2]3}·8H2O

Three novel NiII coordination polymers [Ni2(HCOO)4(H2O)4]n (1), [Na2Ni(btec)(H2O)8]n (2; H4btec = 1,2,4,5-benzenetetracarboxylic acid) and [{Ni(pdc)(H2O)2}·H2O]n (3; H2pdc = pyridine-2,5-dicarboxylic acid) have been hydrothermally synthesized and their structures determined by single-crystal X-ray diffraction. The formate groups in complex 1 bridge the NiII ions to form a infinite 3D structure. Complex 2 also possesses a infinite 3D structure and the coordination environment of the NiII ion is a perfect octahedron. Complex 3 is a 2D infinite coordination polymer. The surface photovoltage spectra of complexes 1–3 indicate that they all show three positive surface photovoltage (SPV) responses in the range of 300–800 nm and all show p-type semiconductor characteristics. Although the intensities of the SPV responses are obviously different, this can mainly be attributed to the difference of their structures. The field-induced surface photovoltage spectra (FISPS) of complexes 1–3 confirm their p-type semiconductor characteristics. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
