Abstract:
The size, shape, and symmetry of cations and anions in ionic liquids determine the adjustable properties of these industrially relevant liquid salts. In this work, we show how the deliberately introduced asymmetry of cations can change and even control the phase behavior and rotational diffusion in protic ionic liquids. The method of choice here is solid-state NMR spectroscopy, which provides structural and dynamic information about the heterogeneous material. In addition, we show that the chosen trialkyl ammonium-based ionic liquids are excellent model systems for studying Coulomb-enhanced hydrogen bonding and anisotropic molecular motion.

Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...
