Ionic liquids (ILs) containing the bis(fluorosulfonyl)imide anion, FSI, have been investigated as electrolytes for metal-air batteries. Full chemical reversibility is found reduction of oxygen to superoxide at 60 °C under short time scale conditions cyclic voltammetry a glassy carbon electrode when IL contains small chain length triisobutyl(methyl)phosphonium rather than pyrrolidinium cation. D...

the article of marc jamoulle shows the importance of the contribution of general practitioners (gps) in improving the quality and the efficiency of the health systems. starting from the concept of quaternary prevention for reducing excessive costs in the preventive procedures, he suggests a change of paradigm in every daily activity of the gp in order to have a stronger ethical approach to the ...

In the title molecular salt, C36H30NP2(+)·C24BF20(-), the P-N bond lengths in the cation are equal [1.573 (2) and 1.572 (2) Å], indicating a resonance structure and the P-N-P bond angle is 144.79 (12)°. In the crystal, weak C-H⋯F interactions link the cations and the anions.

Liquid ion association in ionic liquids (ILs) has been examined using a comprehensive series of electronic structure calculations that measure the relative extents of ion association and probe stabilisation for the photochromic dye nitrobenzospiropyran (BSP) in a range of ILs featuring both long-tailed phosphonium cations and short-tailed imidazolium cations, paired with both chloride and NTf(2...

Two high-salt-content ionic liquid electrolytes with distinct cationic chemistries were compared. The one a phosphonium cation showed superior characteristics, particularly in terms of its enhanced capacity when used lithium metal batteries.

Linking decyl-triphenyl-phosphonium to fluorescein yields a fluorescent probe that accumulates in energized mitochondria, facilitates proton transfer across membranes and stimulates mitochondrial respiration. This features a mitochondria-targeted uncoupler, being of potential interest for therapeutic use against oxidative stress-related diseases.

Various novel hypercrosslinked porous polymers with phosphonium salt incorporated into their networks were developed. These porous materials have high BET surface areas (up to 1168 m(2) g(-1)) and can be used to selectively capture CO2 and efficiently convert CO2 into cyclic carbonates.

A broad range of readily accessible N-sulfonyl imines undergo olefination reaction with nonstabilized phosphonium ylides under mild conditions to afford an array of both Z- and E-isomers of 1,2-disubstituted alkenes, allylic alcohols, and allylic amines in good yields and with greater than 99 : 1 stereoselectivity.
