Abstract

Abstract: The hitherto longest molecular thread-belt assemblies 8, 29, 32 and 43 based on benzene-connected [3.3] metacyclophane units were prepared by means of a repetitive synthetic method. The preparation of difunctionalized [3.3] metacyclophane units (14, 22, 26) succeeded in good yields by an iteration sequence including the cyclization to the cyclophane skeleton and the derivatization of the ester groups. The covalent linkage of the ...
