First report on electrochemical, thermodynamic and structural aspects of the interaction of p-tert-butylcalix[8]arene and cryptands in benzonitrile

p-tert-Butylcalix[8]arene interacts with cryptands 22 and 222 in benzonitrile to give 1 : 1 electrolytes, and thermodynamic, electrochemical and structural aspects of this interaction are reported for the first time; the results suggest that cryptand 222 hosts a proton from the calixarene in its cavity.
