The systematic studies through 1H NMR longitudinal relaxation times (T1) of an ionophoric 1,3-alternate-shaped calix[4]arene ester 1 were reported. The T1 values were measured under proton-noise-decoupling conditions by the inversion-recovery technique. The terminal groups in an ethoxycarbonylmethoxybenzene unit in 1 move vigorously whereas the motion of the central ArCH2Ar moiety is rather suppressed. K+ ion plays an important role as a template ion specifically to freeze the fluctuational motion of these terminal groups. The ethoxycarbonylmethoxybenzene unit features a ‘seesaw motion’ around the ArCH2Ar moiety as central support. It is clear that the molecular motion of the calixarene skeleton is efficiently frozen through complexation with metal cations.
