Silver ion oscillation through calixtube of 1,3-alternate calixcrown-5-azacrown-5 and 1,3-alternate calix-bis-azacrown-5 was investigated by temperature variable 1H NMR experiment. The latter (symmetrical calix-bis-azacrown-5) showed an intramolecular metal ion tunneling through π-basic calixtube while the former did not.
