Abstract
Several quadruply bridged calix[6]arenes were prepared in high yield by the reaction of various 1,4-di-O-alkylated calix[6]arenes with 1,2,4,5-tetraki s-(bromomethyl)benzene in the presence of Cs2CO3. The alkali metal extracti on study established that this compound shows the high selectivity toward C s+ among alkali metal cations. The cesium binding characteristics were inve stigated with H-1 NMR and UV spectroscopy.
