58. There are three types of nomenclatures for these molecules. For example, structure 3, the IUPAC name is pentacyclo-[19.3.1.13,7.115,19]-octacosa-1(25), 3,5,7(28), 9,11,13(27), 15,17,19(26), 21,23-docdecaene; According to Cram's nomenclature, it is [1.1.1.1]metacyclophane (see F. Vögtle Cyclophane Chemistry (English Edition), p. 331, John Wiley & Sons Ltd. p. 1993). Here we chose the simplest one, i.e. Gutsche's nomenclature. They are calix[4]benzene for 3, calix[4]pyridine for 4, calix[4]furan for 5, calix[4]thiophene for 6, calix[4]pyrrole for 7. See F. Vögtle Acc. Chem. Res. 32, 729 (1999) and Ref. 6. All these can be categorized into calix[4]aromatics.
