摘要：

A series of biscalix[4]arenes (2(n)) doubly-bridged with oxyethylene chains at the lower rim have been synthesized. As in conventional ionophoric monocalix[4]arene derivatives, these-compounds showed ion selectivity towards Na+. The H-1 NMR spectroscopic studies established that Na+ and Kf ions complexed with 2(n) oscillate intramolecularly between two calix[4]arene ionophoric sites. Two coalescence temperatures were found in the temperature-dependent 1H NMR spectra in the presence of these metal; cations: the coalescence for the intermolecular metal exchange appears at a high temperature region whereas the coalescence for the intramolecular metal oscillation appears at a low temperature region. These two processes could be discriminated by the difference in the concentration dependence: the intermolecular process is concentration-dependent whereas the intramolecular process is concentration-independent. This is a unique dynamic system in which metal cations jump from one ionophoric site to another ionophoric site in biscalix[4]arenes in the NMR time-scale.
