A Kinetic and Thermodynamic Study of Exciplex Fluorescence Quenching by Ion Pairs
Tetraalkylammonium salts are shown to quench the fluorescence of the pyrene-N,N-dimethylaniline exciplex in solvents of low dielectric constant. Linear Stern-Volmer plots are obtained for quenching of both lifetime and intensity in dioxane. However, mechanistic complications are implied by …

Synthesis of functionalized few layer graphene via electrochemical expansion
… of graphite in organic solvent containing tetraalkylammonium salts, avoiding oxidation of graphene and the associated defect generation encountered with the broadly used Hummer's method. The expansion and charging of the graphite by intercalation of cations facilitates the functionalization …

Phase transfer catalysis: catalyst screening, reaction development, and mechanism analysis
… startling insights. A series of symmetrical, tetraalkylammonium salts were examined for their catalytic and intrinsic reactivity. Tetraalkylammonium phenolate salts were prepared from the corresponding ammonium bromides and their activity was evaluated for the n-butylation of phenol. Small …

Understanding the Structure and Dynamics of Supramolecular Assemblies and Peptides in Solution
… in the absence and presence of different tetraalkylammonium salts is examined to interpret NMR experiments and elucidate the effect of different guests on the role of water molecules in the stability and dynamics of the hexameric capsule.Understanding the structure of proteins is key to …

Structure and Reactivity in Nanostructured Ionic Solvents
… their chemical nature since ILs are pure liquid salts whereas DESs are mixtures. Like ILs, DESs that contain at least one sufficiently amphiphilic component can form bicontinuous nanostructures consisting of polar and non-polar domains. The ability of DESs to form amphiphilic bulk nanostructures …
