  Chelating ability of a conjugated redox active tetrathiafulvalenyl-acetylacetonate ligand

  摘要：

  A novel tetrathiafulvalene (TTF) bearing a conjugated beta-diketone moiety (TTFacacH) has been synthesized and fully characterized. The chelating ability of its enolate anion (TTFacac) has been investigated with [M-II(OAc)(2)center dot xH(2)O](OAc = acetate and M = Zn, Cu and Ni) leading to complexes, where the metal center is coordinated by two TTFacac. Modulation of the redox properties of the TTF can be achieved through the simple change of the two apical ligands which completed the octahedral coordination geometry. This redox active ligand shows promising features for the elaboration of hybrid organic-inorganic building blocks. (c) 2007 Elsevier B.V. All rights reserved.

  of 100 mV s−1. A RhII/RhI redox couple was observed at E°′ = 0.89 V for 3, after both TTF oxidations were completed, and at 0.51 V for 4; this is between the two TTF redox processes. The more difficult oxidation of the RhI center of 3 indicates more effective electron-withdrawing from the RhI center to the first-oxidized TTF+ group at the methine position of the β-diketonato ligand of 3+ than to the
