A supramolecular system of tetrathiafulvalene, assembled by hydrogen bonding, ionic coordination bonding and topological cooperation

Abstract

Solid state and solution chemistry of a supramolecular system, a sodium complex with ligands of tetrathiafulvalene (TTF) dicarboxylate and benzotriazole molecules, have been studied. The well characterized host–guest response in H₂O–CH₃CN (1 ∶ 1 v/v) was monitored by electronic spectra and cyclic voltammetry. The host–guest reaction occurred immediately under the experimental conditions, which took only about 15 min to form high quality and large scale crystals. By the coordination of sodium cations and the water bridges, an unusual one dimensional structure formed. The compound is a coordination bonding, hydrogen-bonding assembled and, especially, topological cooperated supramolecule. The reaction selectivity of the TTF-dicarboxylate with small organic molecules has also been discussed.
