ID coordination polymers

In conclusion, ID coordination polymer [Zn(tmbdc)(dmso)2]-2(DMSO) 2 has been synthesized with 2,3,5,6-tetramethyl-l,4-benzenedicarboxylic acid in DMSO. The structure contains ID chains formed by octahedraly coordinated Zn ions chelated by the carboxyl groups of tmbdc, rather than the 2D (4,4) nets constructed from paddle-wheel SBU of pairs Zn ions as found in [Zn2(bdc)2(dmso)2]-5DMSO 1. Analysis of the structure reveals that the steric hindrance of die four methyl groups of tmbdc determines the coordination environments of the zinc ions and the coordination modes of the carboxyls, and thus the final structures of the coordination polymers. The result also shows that DMSO is a stronger ancillary ligand and is also easier to be included in the structures of coordination polymers, compared to DMF. DMSO can be a better solvent for the syntheses of porous coordination polymers.

Another kind of ID coordination polymer is the ladder structure, this time made up of 3-connected nodes. One connector per node makes up a rung of the ladder and hence the polymer only propagates in one dimension producing a flat ribbon-like structure. With ligands like bpy the... 

The control and fabrication of single compounds, and the organization of metal-organic units in ID coordination polymers or 2D coordination arrays is of interest in metallosuparmolecular engineering on surfaces. The key features and their role in the potential functionality of the particularly versatile nanoporous networks achieved by metal-directed assembly in vacuum are illustrated in Scheme 1. The work on the formation of supramolecular architectures on surfaces containing metal centers will here be divided into the two approaches illustrated in Scheme 2. 

ID coordination polymer assemblies have attracted much attention in the development of new functional materials owing to such properties as zeolitic behavior, conductivity, luminescence, magnetism, spin-crossover, and nonlinear optical effects [76]. ID coordination chains in solution were obtained from Fe and ditopic bis-terpyridines on graphite [109]. Also, polymeric ro-taxane chains consisting of cyclodextrins-dipyridine units connected by coordination with Ni ions [259], and [CuBr-(isoniconitic acid)] polymeric chains [260] were investigated regarding their surface assembly behavior.
