An EPR Investigation of the Kinetics of Inclusion of a Persistent Radical in Water-Soluble Calix
Distinct EPR signals are observed for the free and included species for the inclusion of the neutral benzyl tert-butyl nitroxide probe into a calix[4]arene host in water (shown schematically). Computer simulation of the EPR spectra recorded at various temperature enabled direct determination of the activation and kinetic parameters for this inclusion process.
