Electric, electrochemical and magnetic properties of novel ionic liquid nitroxides, and their use as an EPR spin probe

Abstract

Novel metal-free paramagnetic ionic liquid imidazolium compounds, which contain a chiral cyclic nitroxide unit as the redox and spin sources in the cation, have been prepared, and their first use as an EPR spin probe in diamagnetic ionic liquids as well as their electric, electrochemical and magnetic properties are described.
