Abstract
13C CP/MAS spectroscopy of calix[4]arene-based carceplexes shows that in the solid state the cavity walls of the carcerand are rigid, whereas the pendant groups of the resorcin[4]arene as well as the ends of the propyl goups of the calix[4]arene moiety exhibit some flexibility. Temperature dependent 2H measurements of the DMSO-d6 carceplex reveal that two different sites are present for the DMSO guest with an energy difference of 1.7 kcal mol-1.
