Characterization of Silver Trimethylacetate Complexes with Tertiary Phosphines as CVD Precursors of Thin Silver Films,

CHEMICAL VAPOR DEPOSITION, Issue 1 2005
P. Piszczek
Abstract AgI complexes [Ag(O2CtBu)(PMe3)] (1) and [Ag(O2CtBu)(PEt3)] (2) were used as CVD precursors. Silver films between 30,nm and 100,nm were deposited from the above compounds using hot-wall and cold-wall CVD techniques on Si(111) and Si(100) substrates in the temperature range 180-220,°C, under the reactor pressure 1,3,mbar. Metallic films were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), glow discharge optical emission spectroscopy (GDOES), scanning electron microscopy (SEM), and conductivity measurements.

The relationship between the electrospray ionization behaviour and biological activity of some phosphino Cu(I) complexes

RAPID COMMUNICATIONS IN MASS SPECTROMETRY, Issue 11 2010
Francesco Tisato
Electrospray ionization mass spectrometry was usefully employed for the characterization of three phosphino copper(I) complexes of medicinal interest. This technique revealed that the original [CuL4]+ pro-drugs (L,=,hydrophilic tertiary phosphine) underwent dissociation with production of coordinative unsaturated [CuL3]+ and [CuL2]+ species, which represented key intermediates for the activation of potential biological properties. The more favoured was the displacement of the ligands from the [CuL4]+ parent complex, the more favoured was in turn the possibility for the metal ion to directly interact with biological substrates, including pharmacological targets related to cancer proliferation. An inverse correlation between the stability and the cytotoxic activity of the three copper(I) complexes investigated has been clearly established. Copyright © 2010 John Wiley & Sons, Ltd. [source]
