Molecular recognition and self-assembly special feature: Dynamic combinatorial synthesis of a catenane based on donor-acceptor interactions in water.


ABSTRACT: 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.
