A conformationally preorganized, C s -symmetrical p-tert-butyl-calix[6]-1,4-crown-4-2,6-dioxo-diazacrown-4 with hard and soft ion binding sites at the lower rim is synthesized. The binding sites may complex alkali metal ions or transition metal ions selectively.

Ditopic "hard"-"soft" metal binding-sites composed of four EtS(CH&NHCOCH20groups were designed for the iirst time on a calixl4larene pkform. N = 2 is too short to form a bimetallic complex whereas n = 6 is long enough to accept two metal ions. 1H NMR spectral studies established that although Cdz+ b

1,3-Alternate calix[4]-cyclen-benzo-crown-6 incorporating a cyclen subunit on one side and a benzocrown-6 on the other side of the calix[4]arene framework has been synthesized. Preliminary complexation studies of this macropolycycle with cesium and zinc picrate salts have been carried out by means o
