Four new series of 5,17-(di-ionizable)-25,26,26,28-tetraalkoxycalix[4]arene ligands are prepared. The ionizable groups are carboxylic acid and N-(Z)sulfonyl formamide functions with Z = –Me, –Ph, –C6H4–4-NO2, and –CF3. When the four alkoxy

We report an improved synthesis method for the production of cyclophanes 5, 6, and 7 in higher yields of 71, 98, and 99%, respectively, compared to the previously reported 40, 30, and 70% yields, respectively. Cyclophanes C5, C6, and C7, called corra
