Abstract
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 o r transition metal ions selectively. (C) 2000 Elsevier Science Ltd. All rig hts reserved.
