Preparations, Structures, and Properties of Sulfato-Bridged Dinuclear and Tetranuclear Vanadium(III) Complexes with a Dinucleating Ligand, 2-Oxo-N,N ′-bis(2-pyridylmethyl)-1,3-propanediamine-N,N ′-diacetate

[Full Text PDF(J-STAGE)] Open Access Article
We synthesized dinuclear and tetranuclear vanadium(III) complexes containing an alkoxo-bridging dinucleating ligand, 2-oxo-N,N ′-bis(2-pyridylmethyl)-1,3-propanediamine-N,N ′-diacetate (hpnbpda), and a sulfato group, and determined their structures by X-ray crystallography.

Functional Design of Ionic Liquids
H. Ohno
[Full Text PDF(J-STAGE)] Open Access Article
 |
Ionic liquids, derived from functional salts, are novel liquid materials having characteristics completely different from molecular liquids. The development of materials for electrochemistry is also reviewed.

Versatile Vapochromic Behavior Accompanied by a Phase Change between Charge-Polarization State and Charge-Density-Wave State in a Quasi-One-Dimensional Iodo-Bridged Dinuclear Platinum Mixed-Valence Compound, [{NH3(CH2)5NH3}2][Pt2(pop)4I]·4H2O
M. Yamashita,* K. Takizawa, S. Matsunaga, D. Kawakami, H. Iguchi, S. Takaishi, T. Kajiwara, F. Iwahori, T. Ishii, H. Miyasaka, K. Sugiura, H. Matsuzaki, H. Kishida, and H. Okamoto
[Full Text PDF(J-STAGE)] [Supporting Information] Open Access Article
This communication describes versatile vapochromic behavior that is accompanied by a phase change between charge-polarization (CP) and charge-density-wave (CDW) states with increasing and decreasing temperature in [{NH3(CH2)5NH3}2][Pt2(pop)4I]·4H2O (pop = P2H2O52−) (1).

Great Enhancement in the Oxidation Ability of Dilute Nitric Acid in Nanoscale Water-Droplets of Reverse Micelle Systems

The Br− ion of CTAB surfactant was oxidized into Br2 (or Br3−) in the CHCl3/CTAB/H2O reverse micelle system with W values between 1.0 and 4.0 by dilute nitric acid (0.25–2.5 mol dm−3) at 15–40°C. The change in 1H NMR chemical shift demonstrated the consumption of protons during the oxidation of Br−, but not of Cl−, by dilute HNO3.

pH-Dependent Color-Change Behavior of Bis(o-phenylenediamine)platinum(II) Complex and pH-Dependent Redox of Bis(o-semibenzoquinonediimine)platinum(II) Complex
Y. Konno and N. Matsushita*
[Full Text PDF(J-STAGE)] [Supporting Information] Open Access Article
Bis(o-phenylenediamine)platinum(II) complex (colorless) in an aqueous solution exhibits a color-change behavior either to purple or yellow-green depending on the pH of the solution. The behavior results from the bis(o-semibezoquinonediimine)platinum(II) complex being oxidized by the addition of H+.

Phenalenyl-Based Highly Conductive Molecular Systems with Hydrogen-Bonded Networks: Synthesis, Physical Properties, and Crystal Structures of 1,3- and 1,6-Diazaphenalenes, and Their Protonated Salts and Charge-Transfer Complexes with TCNQ
T. Murata, Y. Morita,* K. Fukui, K. Tamaki, H. Yamochi, G. Saito, and K. Nakasuji*
[Full Text PDF(J-STAGE)] Open Access Article
Hydrogen-bonded charge-transfer complexes of 1,3- and 1,6-diazaphenalene systems were explored as new phenalenyl-based molecular conductors. 1,3- and 1,6-diazaphenalene derivatives constructed various and well-defined assembled structures by intermolecular hydrogen bonds, and formed highly conductive charge-transfer complexes with TCNQ.

Reversible On–Off Photoswitching of Hydrogen Bonding for Self-Assembled Fibers Comprising Physical Gels
M. Moriyama, N. Mizoshita, and T. Kato*
[Full Text PDF(J-STAGE)] Open Access Article
Photo-stimulated reversible association and dissociation of hydrogen bonding have been achieved in a physical gel system. This photoswitching of hydrogen bonding is caused by the changes in molecular polarity of the photochromic azobenzene moieties in the gelator.
