N2 - Ionic liquids (ILs) exhibit a number of unique properties, including formation of various heterogeneities in their liquid and glassy states. Electron Paramagnetic Resonance (EPR) spectroscopy has proven informative in studies of such heterogeneous nanostructures; however it employs additional small paramagnetic molecules – spin probes – dissolved in ILs as reporters. In this work we synthesized two radical-ILs, which include integrated paramagnetic fragments in their structures, and employed them in continuous wave (CW) and pulse EPR studies of structural peculiarities in IL glasses. In this approach no external-to-IL spin probe is required. We have shown that the trends observed with radical-ILs are similar to those obtained previously using external-to-IL spin probes.
