| Abstract: | Co-receptor 1,3-calix4]-di(aza-benzo)crown-crown-6 (1-H) designed with one calix4]arene in a 1,3-alternate conformation and  hard and soft metal ion binding sites has been prepared according to three pathways (A-C). Pathway B, consisting of two different 1 + 1 condensations with ditosylate derivatives, was shown to be the most efficient. |
