Abstract
Conformationally stable, tunable upper-rim calix[4]crowns 3 similar to 7 were synthesized in good yields from dibromodihydroxycalix[4]arene hexyl ether 1 and the picrate extraction experiment showed their highe r affinities for primary ammonium ions compared to those for alkali me tal cations.
