1H and 13C NMR relaxation times (T1) of ethoxycarbonylmethyl derivatives of p-t-butylcalix[n]arenes have been determined at 90 MHz and 36 °C in [2H8]THF. It was found that these calixarenes feature a 'seesaw motion' around the ArCH2Ar linkage as a central support and that this molecular motion is largely suppressed through complexation with Na+.
