Abstract: | The synthesis of new macrocyclic receptors associating the electroactive tetrathiafulvalene unit (TTF) to different polyaza ligands is described. The structure of these receptors varies by the size of the coordinating unit (polyaza chains of various lengths), and by the nature of the latter, since a macrocyclic cyclam or a diazatetraoxa macrocycle derivative has been also introduced. The X-ray diffraction study on a single crystal of one of these receptors, demonstrates the electroactive TTF framework to be planar enough to present the expected reversible electrochemical behaviour. A preliminary study of the coordination ability of these polyazaTTF receptors is also given. To cite this article: G. Trippé et al., C. R. Chimie 6 (2003). |
