GaN nanoparticles were prepared via microwave-assisted synthesis in ionic liquids. They are well-crystallized (β-GaN) and nanosized (3–8 nm), exhibit a band gap of 3.9 eV, and show green emission with a remarkable quantum yield of 55%.

The dry chemical method is developed to fabricate CuO nanostructures via microwave assisted irradiation in ionic liquid 1-butyl-3-ethyl imidazolium tetrafluoroborate ([BMIM][BF4]). Both nanoparticles (20 nm in size) and nanorods (10-20 nm in diameter and 100-200 nm in length) of monoclinic CuO were obtained. The as samples were characterized by FTIR, XRD, TEM, SADE. The morphologies of the nanostructures can be controlled by the amount-tuning of NaOH and ionic liquids. The growth mechanism of CuO nanostructures is investigated.

ABSTRACTA perfluorinated ionic liquid, 1-(perfluorohexyl)-3-methylimidazolium iodide, was synthesized via microwave reaction and compared to a non-fluorinated analog. Typically, the synthesis of fluorinated ionic liquids involves long reaction times and multiple steps. We have demonstrated a shortened synthesis and a more straightforward procedure, by using a microwave reactor for the microwave-assisted synthesis of 1-(perfluorohexyl)-3-methylimidazolium iodide. The addition of fluorinated alkyl chains on imidazolium ionic liquid cations increases the molecular free volume of the ionic liquid which is beneficial for increasing CO2 physisorption. Computational and experimental data shows an increased CO2 solubility and capacity for fluorinated ionic liquids. The perfluoroalkyl functionalized ionic liquid is characterized using 1H and 19F NMR spectroscopy, FTIR spectroscopy, and DSC. By DSC, a crystallization onset is near -31 °C and while the onset of the melting point between -30 and -17 °C.
