Abstract
Differential pressure effect was found in the inclusion equilibrium of bimo dal inclusion (phenyl-in and t-butyl-in) complexes of beta-cyclodextrin wit h the free-radical probe diphenylmethyl t-butyl nitroxide. A high-pressure electron paramagnetic resonance (EPR) system was employed to determine the shift of the EPR spectra under high static pressure. With increasing extern al pressure, the equilibrium between phenyl-in and t-butyl-in complexes shi fts to the t-butyl-in side.
