Dynamic combinatorial synthesis of a catenane based on donor–acceptor interactions in water

By Ho Yu Au-Yeung, G. Dan Pantoş and Jeremy K. M. Sanders


A new type of neutral donor–acceptor [2]-catenane, containing both complementary units in the same ring was synthesized from a dynamic combinatorial library in water. The yield of the water soluble [2]-catenane is enhanced by increasing either building-block concentrations or ionic strength, or by the addition of an electron-rich template. NMR spectroscopy demonstrates that the template is intercalated between the 2 electron-deficient naphthalenediimide units of the catenane
