dc.description.abstract New ionic liquids (ILs) from 1,10-Phenanthroline and 4, 4’- Bipyridine have been synthesized. The synthetic procedure is based on the typical alkylation plus anion methathesis steps common to commonly used ionic liquids. Optimization of the reaction conditions allows the successful monoalkylation of both 1, 10-Phenanthroline and 4, 4’- Bipyridine which is key for the low melting points observed. All new ionic liquids have been fully characterized using NMR, MS and CHN microanalysis. The phase behavior and decomposition temperatures of these ILs have been investigated using DSC and TGA. The ionic liquids were also analyzed using X-ray photoelectron spectroscopy (XPS). The binding energy data obtained in this research may find future use as a standard list of binding energies for 1, 10-Phenanthrolinium and 4, 4’-Bipyridinium based ionic liquids and other related compounds. The solvent ability of these new ionic liquids was tested. Nanoparticle stabilizers such as 1, 10-Phenanthroline and its metal complexes were dissolved at high concentrations in 1, 10- Phenanthrolinium based ionic liquids and metal salts have shown very high solubilities in 4, 4’-Bipyridinium based ionic liquids. These dissolving abilities make the new ionic liquids very promising for applications such as catalysis, nanoparticle synthesis, electrodeposition or metal extraction. en_US
