Abstract

A cyclic network of chemical reactions has been conceived for exchanging the dynamic behaviour of diacylaminopyridine-based rotaxanes and surrogates. X-ray diffraction studies revealed the intercomponent interactions in these interlocked compounds and were consistent with those found in solution by dynamic NMR experiments. This particular binding site was incorporated into a molecular shuttle enabled for accessing to two states with an outstanding positional discrimination through chemical manipulation. Furthermore, the ability of the diacylaminopyridine domain to associate with external binders with a complementary array of HB donor and acceptor sites was exploited for the advance of an unprecedented electrochemical switch operating through a reversible anion radical recognition process.
