supercritical CO2 (sc CO2) soluble organometalliccomplexes. To explore solubility in these media, the synthesis of a number of organometalliccomplexes containing the phosphine ligand (CF3(CF2)5(CH2)2)3P 2, is reported. The platinum(II) complex, trans-Pt[(CF3(CF2)5(CH2)2)3P]2Cl21, has been synthesized, isolated, and characterized by X-ray crystallography and 31P-NMR spectroscopy.

The salts can be quite efficient at extracting picrate from water into CF3C6F5 (97–86 % for 2, 4, 9, 10) or CF3C6H5 (85–66 % for 2-4), demonstrating their potential for phasetransfer catalysis.

The electrodes exhibited the theoretically expected “Nernstian” response slopes, and their selectivities for different anions were determined. For environmental analysis, the selective detection of perfluorooctanesulfonate and perfluorooctanoate is of particular interest. While previously reported electrodes based on a fluorophilic
