Nano-structured copper oxides were successfully prepared through direct calcination of 1D ladderlike metal-organic framework [Cu2(btec)(2,2'-bipy)2]∞, (btec = 1,2,4,5-benzenetetracarboxylate and 2,2'-bipy = 2,2'-bipyridine) and porous coordination polymer [Cu(BDC)(bipy)](BDCH2), (BDC = 1,4-benzenedicarboxylate; bipy = 4,4'-bipyridine). The nano-structure of the as-synthesized samples are charac...

An unsymmetric tetracarboxylic ligand collaborates with 4,4'-bipyridine to induce spontaneous resolution to form homochiral 3D coordination frameworks, while the use of longer dipyridyl ligands instead of 4,4'-bipyridine leads to isoreticular but heterochiral frameworks.

In bi- and trimetallic Pt-bipyridine-acetylide/Ru-bipyridine complexes the intermetallic Pt-Ru distance is approximately 9 è, and complete Pt-->Ru energy transfer is observed with sensitization of the Ru-based luminescence.

Herein, we report for the first time the use of bipyridine-based hydrogel for selective and visible detection and absorption of Cd(2+). At low concentrations, hydrogelator 1 was applied for selective detection of Cd(2+) in vitro and in living cells with high sensitivity. In the absence of metal ions, 1 is nonfluorescent at 470 nm. Upon addition of metal ions, 1 selectively coordinates to Cd(2+)...

Three homochiral cadmium camphorates have been prepared through temperature-dependent synthesis; they form 3D homochiral networks without the crosslinking or pillaring functions of auxiliary neutral bipyridines and exhibit various degrees of charge separation associated with the degree of hydration and controllable by temperature.

Collar and tie men: the smallest trefoil knot reported to date has been prepared by an active metal template synthesis. Copper(I) ions are able to constrain the well-designed structure so that it can form the loops by complexing to the bipyridine moieties in the core of the thread and the two ends of the entangled lace on opposite faces of the loop, before acting as a catalyst to close the lace.

In the title compound, [Cu(C(5)H(8)NS(2))I(C(10)H(8)N(2))], the Cu(II) ion is coordinated by one iodide ion, two N atoms of the bipyridine ligand and two S atoms from the pyrrolidine-1-dithio-carboxyl-ate ligand in a distorted square-pyramidal environment.

The reduction of Triphos [PhP(CH(2)CH(2)PPh(2))(2)] iron halide complexes has been explored, yielding formally zerovalent (κ(3)-Triphos)Fe(κ(2)-Triphos) and (κ(3)-Triphos)Fe(κ(2)-Bpy). Electrochemical analysis, coupled with the metrical parameters of (κ(3)-Triphos)Fe(κ(2)-Bpy), reveal an electronic structure consistent with a π-radical monoanion bipyridine chelate that is antiferromagnetically ...

A linear template in the form of a bipyridine has been developed and is shown to direct a single-crystal-to-single-crystal [2 + 2] photodimerisation of a dicarboxylic acid.

Multiconfigurational, intermediate valent ground states are established in several methyl-substituted bipyridine complexes of bis(pentamethylcyclopentadienyl)ytterbium, Cp2*Yb (Me(x)-bipy). In contrast to Cp2*Yb(bipy) and other substituted-bipy complexes, the nature of both the ground state and the first excited state are altered by changing the position of the methyl or dimethyl substitutions ...
