Abstract
1,3-Dipropyloxycalix[4]arene dibenzocrown ethers were synthesized in the fixed 1,3-alternate conformation by the reaction of 1,3-dipropyloxycalix[4]arenes with a dibenzo dimesylates. Complexation toward alkali metal ions using ISEs showed a high cesium selectivity. Conformational flexibility of the corresponding 1,3-alternate calixcrown ether (4) with respect to the NMR time scale is found to depend on the temperature and polarity of the NMR solvent.
