Hydrogen bonding and π-π interactions in imidazolium-chloride ionic liquid clusters.

Physical Chemistry, Chemical Physics - PCCP, 2015
A systematic electronic structure analysis of hydrogen bonding (H-bonding), anion-π(+) and π(+)-π(+) interactions present in [C1C1im]Cl ion-pairs (IPs) and selected [C1C1im]2Cl2 IP-dimers has been carried out. Interactions have been characterised using a

Competitive pi interactions and hydrogen bonding within imidazolium ionic liquids.

Physical Chemistry, Chemical Physics - PCCP, 2014
In this paper we have explored the structural and energetic landscape of potential π(+)-π(+) stacked motifs, hydrogen-bonding arrangements and anion-π(+) interactions for gas-phase ion pair (IP) conformers and IP-dimers of 1,3-dimethylimidazolium ...

The importance of timescale for hydrogen bonding in imidazolium chloride ionic liquids.

Physical Chemistry, Chemical Physics - PCCP, 2014
Hydrogen bond (H-bond) dynamics have been investigated for "hot" 1-ethyl-3-methylimidazolium chloride and "cold" 1-butyl-3-methylimidazolium chloride ionic liquids (IL).

Efficient and Energy-Saving CO2 Capture through the Entropic Effect Induced by the Intermolecular Hydrogen Bonding in Anion-Functionalized Ionic Liquids.

Journal of Physical Chemistry Letters, 2014
A strategy for improving the capture of CO2 was developed through the entropic effect by tuning the geometric construction of anion-functionalized ionic liquids.
