The self-assembly of a highly ordered [2]catenane

Template-directed synthesis has been used to construct a [2]catenane in which the two molecular components, the cyclobis(paraquat-p-phenylene) tetracation and 1,5-dinaphtho-38-crown-10, are found to be ordered non-covalently with respect to each other in both the solid (by X-ray crystallography) and solution (by NMR spectroscopy) states and to influence each other to the extent of establishing electrochemical gradients for the stepwise one electron reductions of the two paraquat units.

Ferrocenyldimethyl-[2.2]-cryptand: solid state structure of the external hydrate and alkali and alkaline-earth-dependent electrochemical behaviour

1,1′-(1,4,10,13-Tetraoxa-7,16-diazacyclooctadecane-7,16-diyldimethyl)ferrocene, ferrocenyldimethyl-[2.2]-cryptand 1, binds water on its external face rather than internally and exhibits electrochemical behaviour that is strongly dependent on alkali and alkaline earth metal cations.

FERROCENE AS THE CENTRAL UNIT IN NOVEL, REDOX-SENSITIVE LIGANDS, MONOMERS, AND RECEPTORS

The ferrocene system is remarkable for its structure, thermal stability, and chemical versatility. We describe in this article, diverse applications of ferrocene in the preparation of novel structures for use as cation binders, small molecule receptors, and in the formation of membranes.
