Dialkoxycalix[4] arene dibenzocrown ethers (6-9) were successfully synthesized in the fixed 1,3-alternate conformation, with greater than 90% yields by reaction of the corresponding 1,3-dialkoxycalix[4]arenes 2-5 with dibenzodimesylate 13 in acetonitrile as a solvent in the presence of cesium carbo
Two 1,3-alternate calix [4]arene-biscrowns with one proton-ionizable group and two dibenzocrown-6-ether units are synthesized. The compounds exhibit high Cs + extraction efficiency and selectivity. Cs + /Na + and Cs + /K + selectivities for the new N-(trifluoromethylsulfonyl)carbamoyl-substituted ca
