Synthesis and characterization of Pt(0) nanoparticles in imidazolium ionic liquids

Article Abstract:

The controlled decomposition of [Pt.sub.2][(dba).sub.3] (dba = dibenzylideneacetone) dispersed in 1-n-butyl-3-methylimidazolium tetrafluoroborate (BMI.B[F.sub.4]) and hexafluorophosphate (BMI.P[F.sub.6]) ionic liquids in the presence of cyclohexene by molecular hydrogen have produced Pt(0) nanoparticles. The SAXS analysis has shown the formation of a semi-organized ionic liquid layer surrounding the metal particles with an extended molecular length of around 2.8 nm in BMI.B[F.sub.4] and 3.3 nm in BMI.P[F.sub.6].

Terahertz time-domain spectroscopy of imidazolium ionic liquids

Article Abstract:

Terahertz time-domain spectroscopy (THz-TDS) is used to measure the THz complex dielectric spectra of imidazolium ionic liquids. The results have shown that the interion vibrations have contributed to the THz dielectric spectra, indicating that even in the liquid phase the ionic liquids have local structures similar to their solid-phase structures.

Relative volatilities of ionic liquids by vacuum distillation of mixtures

Article Abstract:

The determination of the relative volatilities of a variety of common ionic liquids (ILs) revealed ILs based on imidazolium and pyridinium cations to be more volatile than ionic liquids based on ammonium and pyrrolidinium cations, regardless of counterions present.
