The synthesis and characterization of a novel class of highly-metallized, redox-active polyelectrolytes that employ phosphorus as a scaffold for the installation of transition metals is described. Pyrolysis of thin films of the title polyelectrolytes resulted in the production of magnetite crystallites and ill-defined carbon-, phosphorus- and oxygen-rich phases in char yields of nearly 50%.

Ionic liquid electrolytes based on a number of imidazolium, quaternary ammonium and phosphonium cations have been developed for porphyrin dye sensitised solar cells yielding efficiencies of up to 5.2% at 0.68 Sun.

The first examples of arylphosphonium salts containing a dicarba-closo-dodecaborane(12) (closo-carborane) are reported; in contrast to the 1,12-carborane derivative, the 1,2- and 1,7-isomers undergo a facile deboronation reaction in polar solvents to afford the corresponding nido-carborane phosphonium zwitterions.

In the crystal structure of the title compound, [Ru(C(4)H(6)BN(6))H(C(18)H(15)P)(2)(CO)]·C(2)H(3)N, discrete mononuclear complexes are found in which the Ru atom is coordinated by two triphenyl-phosphine (PPh(3)) ligands, one dihydro-bis(1,2,4-triazol-1-yl)borate ligand, one carbonyl ligand and one hydride atom within slightly distorted octa-hedra. The two P atoms of the PPh(3) ligands are tran...

The crystal structure of the title compound, [Os(C(6)H(7)S)Cl(C(18)H(15)P)(2)(CO)], confirms the formulation as an osmabenzene. There is a slightly distorted octa-hedral coordination environment at the Os(II) ion, with the triphenyl-phosphane ligands mutually trans and the chloride cis to the carbon bearing the -SMe substituent. Within the metallacyclic ring, the C-C distances are appropriate f...

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.

The title compound, [Ni(C(12)H(9)O)Cl(C(18)H(15)P)(2)]·CH(2)Cl(2), was synthesized from the reaction between 1-acetyl-4-chloro-naphthalene, NiCl(2)·6H(2)O and triphenyl-phosphine (PPh(3)) in ethanol. The compound contains one crystallographically unique nickel ion in a pseudo-square-planar geometry.
