Abstract
Calix[4]arene units functionalized at the 1,3-positions of the upper r im with amido groups, -NHC(O)X, act as neutral, hydrogen-bonding recep tors for hydrogen sulfate, dihydrogen phosphate, acetate, benzoate, ni cotinate, oxalate, terephthalate, isophthalate and fumarate with bindi ng strength and selectivity tunable by varying the electron-withdrawin g ability of the terminal substituent X (X = CH2Cl, CHCl2, CCl3).
