The antibacterial activity of 4,4'-bipyridinium amphiphiles with conventional, bicephalic and gemini architectures.

Melissa C Grenier et al.

Bioorganic & medicinal chemistry letters, 22(12), 4055-4058 (2012-05-15)

Dialkyl 4,4'-bipyridinium compounds are widely employed for their useful redox properties, and are commonly known as viologens due to their intense coloration upon reduction. Despite their prevalence and amphiphilic nature, the antibacterial activity of these compounds remains largely unreported. We

Differences of crystal structure and dynamics between a soft porous nanocrystal and a bulk crystal.

Yuh Hijikata et al.

Chemical communications (Cambridge, England), 47(27), 7632-7634 (2011-06-11)

We have demonstrated downsizing effects of the soft porous crystal, [Zn(isophthalate)(4,4'-bipyridyl)](n) (CID-1), on the adsorption behavior between CID-1 and CID-1 nanocrystal (NCID-1). The difference results from the packing crystal structures and the dynamics of the frameworks.

Direct synthesis of aqueous quantum dots through 4,4'-bipyridine-based twin ligand strategy.

Mausam Kalita et al.

Inorganic chemistry, 51(8), 4521-4526 (2012-03-27)

We report a new class of derivatized 4,4'-bipyridinium ligands for use in synthesizing highly fluorescent, extremely stable, water-soluble CdSe and CdTe quantum dots (QDs) for bioconjugation. We employed an evaporation-condensation technique, also known as solvated metal atom dispersion (SMAD), followed

Synthesis, crystal structures and magnetic properties of dinuclear copper(II) compounds with NNO tridentate Schiff base ligands and bridging aliphatic diamine and aromatic diimine linkers.

Luca Rigamonti et al.

Dalton transactions (Cambridge, England : 2003), 40(13), 3381-3393 (2011-02-23)

The synthesis and the characterization of new dinuclear copper(II) compounds of general formula [(L(a-d))(2)Cu(2)(μ-N-N)](ClO(4))(2) (1-6) with either neutral aliphatic diamine (N-N = piperazine, pip) or aromatic diimine (N-N = 4,4'-bipyridine, 4,4'-bipy) linker are reported. The copper ligands L(-) (L(a-) =

Investigation of supramolecular interaction in 4, 4′-bipyridine crystal by hydrostatic pressure spectroscopies.

Li A, et al.

Spectrochimica Acta. Part A, Molecular and Biomolecular Spectroscopy, 202(40), 70-75 (2018)

Stepwise preparation and characterization of molecular wires made of zinc octaethylporphyrin complexes bridged by 4,4'-bipyridine on HOPG.

Quirina Ferreira et al.

Nanotechnology, 22(43), 435604-435604 (2011-10-06)

Molecular-scale devices can be made using a step-by-step procedure, in a controllable and highly versatile way. In this report, we describe the growth of molecular wires (MW) from zinc (II) octaethylporphyrin (ZnOEP) assembled on highly oriented pyrolytic graphite (HOPG) by

Redox-Induced Molecular Metamorphism Promoting a Sol/Gel Phase Transition in a Viologen-Based Coordination Polymer.

Christophe Kahlfuss et al.

Chemistry (Weinheim an der Bergstrasse, Germany), 24(49), 13009-13019 (2018-07-28)

We have developed a strategy enabling control over the organization of ditopic molecular tectons within a palladium-based self-assembled system. The key electron-responsive sub-unit is a viologen-based mechanical hinge that can toggle under electric stimulation between a folded and a stretched

Antimicrobial activity of organotin(IV) complexes with the ligand benzil bis(benzoylhydrazone) and 4,4'-bipyridyl as coligand.

Elena López-Torres et al.

Journal of inorganic biochemistry, 105(5), 600-608 (2011-03-30)

Several methyltin(IV) and butyltin(IV) complexes with the ligand benzil bis(benzoylhydrazone) and 4,4'-bipyridyl as coligand were synthesised and characterized by elemental analysis and by IR, (1)H, (13)C and (119)Sn NMR spectroscopies. Some of them were also analyzed using single crystal X-ray
