This report describes both the application of the concepts of supramolecular chemistry to control the reactivity of organic free radical and how Electron Paramagnetic Resonance (EPR) methods have been extensively used for detecting and identifying non covalent assemblies in solution and for clarifying their structure and properties. It will shown how hydrogen-bonding can modulate free-radical properties; how halogen-bonding can be used to prepare supramolecular structure containing nitroxide radicals with particular spin orientations; how the formation of host-guest complexes or the properties of self-assembled monolayer can be investigated by EPR spectroscopy; how radical cations can be employed to prepare very sophisticated molecular devices. Finally, a short description of the effects of confined space like zeolites on radical-radical reactions is provided.

Abstract

This report describes both the application of the concepts of supramolecular chemistry to control the reactivity of organic free radical and how Electron Paramagnetic Resonance (EPR) methods have been extensively used for detecting and identifying non covalent assemblies in solution and for clarifying their structure and properties. It will shown how hydrogen-bonding can modulate free-radical properties; how halogen-bonding can be used to prepare supramolecular structure containing nitroxide radicals with particular spin orientations; how the formation of host-guest complexes or the properties of self-assembled monolayer can be investigated by EPR spectroscopy; how radical cations can be employed to prepare very sophisticated molecular devices. Finally, a short description of the effects of confined space like zeolites on radical-radical reactions is provided.
