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

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.

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

Smoothing the single-crystal to single-crystal conversions of a two-dimensional metal-organic framework via the hetero-metal doping of the linear trimetallic secondary building unit.

Meng-Yao Chao et al.

Dalton transactions (Cambridge, England : 2003), 47(38), 13722-13729 (2018-09-15)

The two-dimensional (2D) metal-organic framework (MOF) [Cd2.25Co0.75(BTB)2(DEF)4]·2(DEF)0.5 (1a, BTB = benzene-1,3,5-tribenzolate; DEF = N,N'-diethylformamide) featuring linear trimetallic cluster secondary building units (SBUs) and replaceable DEF solvates reacts smoothly with dipyridyl ligands DPS, DPDS, and BIPY (DPS = 4,4'-dipyridyl sulfide; DPDS

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

High-performance liquid chromatography enantioseparation of atropisomeric 4,4'-bipyridines on polysaccharide-type chiral stationary phases: Impact of substituents and electronic properties.

Paola Peluso et al.

Journal of chromatography. A, 1251, 91-100 (2012-07-10)

The high performance liquid chromatography (HPLC) enantioseparation of eleven atropisomeric 4,4'-bipyridines was performed in the normal and polar organic phase mode using three cellulose-based chiral stationary phases (CSPs), namely Lux Cellulose-1, Lux Cellulose-2, Lux Cellulose-4, and two amylose-based CSPs, Chiralpak

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

Single molecule dynamics at a mechanically controllable break junction in solution at room temperature.

Tatsuya Konishi et al.

Journal of the American Chemical Society, 135(3), 1009-1014 (2012-10-18)

The in situ observation of geometrical and electronic structural dynamics of a single molecule junction is critically important in order to further progress in molecular electronics. Observations of single molecular junctions are difficult, however, because of sensitivity limits. Here, we
