چکیده

Microwave reaction of Ln(OAc)(3).xH(2)O, Ln = Gd, Eu; OAc = acetate) with and in the ionic liquid [C(4)mim][BF(4)] (C(4)mim = 1-butyl-3-methylimidazolium) allows the fast and efficient synthesis of small, uniform, oxygen-free lanthanide nanofluorides with excellent photophysical behaviour. For GdF(3) : Eu(3+) nanoparticles a quantum efficiency of up to 145% was determined.

Microwave irradiation for the facile synthesis of transition-metal nanoparticles (NPs) in ionic liquids (ILs) from metal-carbonyl precursors and Ru-, Rh-, and Ir-NP/IL dispersions as biphasic liquid-liquid hydrogenation nanocatalysts for cyclohexene.

Stable chromium, molybdenum, tungsten, manganese, rhenium, ruthenium, osmium, cobalt, rhodium, and iridium metal nanoparticles (M-NPs) have been reproducibly obtained by facile, rapid (3 min), and energy-saving 10 W microwave irradiation (MWI) under an argon atmosphere from their metal-carbonyl precursors [M(x)(CO)(y)] in the ionic liquid (IL) 1-butyl-3-methylimidazolium tetrafluoroborate ([BMI...

Stereoselective iron-catalyzed alkyne hydrogenation in ionic liquids.

Iron(0) nanoparticles in ionic liquids (ILs) have been shown to catalyse the semi-hydrogenation of alkynes. In the presence of a nitrile-functionalised IL or acetonitrile, stereoselective formation of (Z)-alkenes was observed. The biphasic solvent system allowed facile separation and re-use of the catalyst.

Microsecond charge separation upon photoexcitation of gold nanoparticles in imidazolium ionic liquids.

Gold nanoparticles (npAu, 5 nm diameter) stabilized by hexanethiol and dodecanethiol do not exhibit in THF upon laser flash excitation (355 nm) any detectable transient in the microsecond timescale. However, using octadecanethiol as npAu ligand, a weak signal attributed to THF solvated electrons was observed after excitation 355 nm. In contrast, irrespective of the alkyl length of the thiol lig...
