Synthesis and investigation of clusters of like-charged ions in OH-functionalized ionic liquids

Universität Rostock, 2019

Abstract: In this work, we systematically investigated the formation of cationic clusters in OH-functionalised ionic liquids (ILs) using a plethora of experimental and theoretical methods. The synthesis and characterization of well-suited sets of ILs was followed by a comprehensive study of cationic clusters and their influencing factors in the gas phase, the condensed phase and at the solid/liquid interface. Infrared spectroscopy, neutron diffraction and quantum chemical methods showed that cooperative hydrogen bonding in cationic clusters is counterintuitively stronger than between cation and anion.
