Ring-opening-metathesis polymerization (ROMP) was used for the preparation of a dipyridylcarbamide-functionalized polymer suitable for solid-phase extraction of metal ions from aqueous solutions. Resins were prepared by the copolymerization of the functional monomer. N,N-di-2-pyridyl- endo-norborn-2-ene-5-carboxamide (I) with 1,4,4a,5,8,8a-hexahydro-l,4,5,8- exo-endo-dimethanonaphthalene (II), using the welldefined Schrock catalyst Mo(N-2,6-i-Pr2C6H3)CHCMe2Ph(OCMe(CF3)2)2 (III). The polymerization proceeds in a living manner, allowing the stoichiometric buildup of polymers. NMR investigations proved the expected backbone structure of the resulting polymers, where the binding site of the monomer remains unaffected in course of the polymerization. The new materials were investigated in terms of their complexation behavior versus a large Variety of mono-, di-, tri-, and tetravalent metal ions employing UV-vis spectroscopy as well as AAS and ICP- OES techniques. The polymer-bound dipyridylamide ligand showed excellent selectivity toward Hg2+ and Pd2+, allowing the selective extraction of both divalent metal ions over a broad range of concentrations from complex mixtures. Due to the stability of the resulting complexes, high loadings of the material with both metals were achieved. To elucidate the chemistry of complexation, X-ray structures of compound (I) as well as ESI-MS investigations of the complex of I with Pd2+ were performed. I crystallized in the monoclinic space group P21/c, and forms 1:1 complexes with Pd2+ under conditions identical to the SPE experiments.

The complexes are prepared by the reaction between [Ag2[B10H10]]and ligand L in organic solvents. It is found that polymeric and binuclear complexes are selectively formed depending on the solvent used. When the reaction proceeds in acetonitrile, polymeric complexes are isolated. When DMF is used, binuclear complexes are formed which explains by the complete dissociation of the starting [Ag2[B10H10]]complex.

Two human GlcNAc-6-sulfotransferases, CHST2 and HEC-GlcNAc6ST, have been recently identified as possible contributors to the inflammatory response by virtue of their participation in L-selectin ligand biosynthesis. Selective inhibitors would facilitate their functional elucidation and might provide leads for antiinflammatory therapy. Here we investigate the critical elements of a disaccharide substrate that are required for recognition by CHST2 and HEC-GlcNAc6ST. A panel of disaccharide analogues, bearing modifications to the pyranose rings and aglycon substituents, were synthesized and screened for substrate activity with each enzyme. Both GlcNAc-6-sulfotransferases required the 2-N-acetamido and 4-hydroxyl groups of a terminal GlcNAc residue for conversion to product. Both enzymes tolerated modifications to the reducing terminal pyranose. Key differences in recognition of an amide group in the aglycon substituent were observed, providing the basis for future glycomimetic inhibitor design.

Two new fluorescence turn-on chemosensors for cyanide based on dipyridylamine substituted aurone moiety have been synthesized. The strong yellow-green fluorescence of the compounds were completely quenched after the addition of Cu(II) ions because of the complexation between the compounds and Cu(II) ions and were almost recovered after the addition of cyanide owing to the strong bonding ability between cyanide and Cu(II) ions, which lead to the removal of copper ions from the complexes. The chemosensors exhibit good repeatability.

The role of hetero-atom manipulation/hetero-aryl group insertion in the triarylamine to obtain hetero triarylamine as a donor in highly efficient photosensitizers was investigated to study the structure-efficiency relationship in dye-sensitized solar cells (DSSCs). A newly synthesized sensitizer was explored containing N-phenyl-N-(pyridin-2-yl) pyridine-2-amine (DPPA) and N-(pyridin-2-yl)-N-(thiophen-2-yl) pyridine-2-amine (DPTA) as the donor along with a strong electron-withdrawing cyano group (-CN) as the auxiliary acceptor group and cyanoacetic acid and rhodamine-3-acetic acid as anchoring groups. The triphenylamine donor was manipulated for the first time with the insertion of a nitrogen atom in the aryl ring for DSSCs. These hetero-aryl-based sensitizers showed a significant improvement in the photophysical as well as photovoltaic performance. The replacement of cyanoacetic acid by rhodanine-3-acetic acid as an anchoring unit resulted in a significant red-shift in absorption as well as emission maxima. The methylene group in rhodanine-3-acetic acid interrupted the LUMO delocalization on the anchoring group in sensitizers DP3 and DP4, as shown by DFT calculations. The presence of cyanoacetic acid in sensitizers DP1 and DP2 showed effective charge transfer from HOMO to LUMO and efficient electron injection from LUMO to the conduction band of the TiO2 semiconductor. The sensitizer DP2 showed a maximum efficiency of 4.7%, a short-circuit current Jsc = 11.78 mA cm-2, an open-circuit voltage Voc = 0.608 V and a fill factor FF = 0.62. The enhanced efficiency of sensitizer DP2 was attributed to the presence of the strong electron-withdrawing cyanoacetic acid anchoring group and the presence of the thiophene linker at the N-aryl core.

The development of new methods for linking sugars to heterocycles and peptides is an attractive area of research because glyco-conjugates play important roles in biology and medicine and are indispensable tools for probing several processes. Herein we report a one-pot, three-component sequential procedure for the synthesis of a novel class of glyco-conjugates, i.e. glyco-hydantoin conjugates, in high yields and very mild conditions, using readily accessible starting materials. We also demonstrated that some of the glyco-hydantoin conjugates obtained are synthons for the preparation of a novel class of glyco-pseudopeptides in which the amino acid is tethered to the sugar through the hydantoin ring.
