K. Ohkubo, T. Nanjo, and S. Fukuzumi*
[Full Text PDF(J-STAGE)] [Supporting Information]
9-Mesityl-10-methylacridinium ion (Acr+–Mes) acts as a photocatalyst for the oxygenation of triphenylphosphine with O2 via radical coupling of triphenylphosphine radical cation and O2•− to produce triphenylphosphine oxide. Photooxidation of benzylamine with O2 also occurs to yield PhCH2N=CHPh and hydrogen peroxide.

[Full Text PDF(J-STAGE)] [Supporting Information]
|
|
A zinc porphyrin–fullerene dyad with a disilane as a σ-conjugated linker has been newly synthesized. Photoinduced electron transfer and energy-transfer processes of the dyad were revealed by time-resolved fluorescence and transient absorption measurements.

A New Salt Bridge Based on the Hydrophobic Room-Temperature Molten Salt

T. Kakiuchi* and T. Yoshimatsu
[Full Text PDF(J-STAGE)]
A conceptually new salt bridge based on a hydrophobic room-temperature molten salt (ionic liquid), 1-octyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, exhibits a stable phase-boundary potential, which is little affected by the type and concentrations of electrolytes in a sample solution. The gelation of the molten salt does not affect the phase-boundary potential. The new salt bridge is free from most of the problems inherent to KCl-based salt bridges.

[Full Text PDF(J-STAGE)]
|
|
In situ observation of the deuterium transfer in the crystalline-state 4–1 photoisomerization of a partially deuterated 4-cyanobutyl cobaloxime complex by neutron diffraction clearly suggests a novel reaction machanism, “alkyl turn” isomerization.

[Full Text PDF(J-STAGE)]
Hybrid films of mesoporous silica with guest porphyrin derivatives ([M(tmpyp)]4+) and titania nanosheets accommodating guest methyl viologen (MV2+) were synthesized. Upon UV and visible light irradiation, the oxidation of [M(tmpyp)]4+ and reduction of MV2+ were observed, indicating that photoinduced electron transfers could be achieved for these hybrid films.

Electromagnetophoretic Measurements of Adsorption Forces of Polystyrene Microparticles on Silica Surfaces in Surfactant Solutions

Y. Iiguni and H. Watarai*
[Full Text PDF(J-STAGE)]
A new technique for the measurement of adsorption force of a microparticle in an electrolyte solution was developed using electromagnetophoretic force. The adsorption forces of polystyrene particles to the bare inner walls and modified inner walls of a fused-silica capillary were determined by this method in the absence and in the presence of surfactants.
