We found that the addition of alkali salts significantly increased the binding between p-sulfonatocalix[8]arene and a guest group. The change in ionic strength of the solution appears to drive the functional group in the probe deep into the calixarene cavity, making it possible to detect the group in complex by using ESR spectroscopy.
