We are investigating in the supramolecular chemistry of 8-hydroxyquinoline derivatives regarding the metal coordination 3 as well as the hydrogen bonding 4., 5. and 6. ability of these molecules. In an ongoing project we study the dimerization behavior of 8-hydroxyquinoline 4 and of its derivatives to use this for the formation of hydrogen bonded polymers in the solid state. 5 Introduction of further hydrogen bonding donor/acceptor sites in the periphery of ...
