Abstract
The synthesis as well as the solution characterization of
electroactive assemblies associating the TTF core and N-ligands are
presented. Two families of ligands L1 and L2 have been
designed for the coordination of transition metals. Polyaza-macrocycles
L1 and notably N
4 (cyclam) (L1a) or N
2O
4
(L1c) macrocyclic units were grafted to the TTF framework under
high pressure conditions. The introduction of the pyridyl moiety has been
realized on the periphery of the TTF skeleton to give rise to the new
electroactive ligand L2. Ligands L1 and L2 have
been electrochemically characterized, including their ability to coordinate
metal cations.
Key words. Tetrathiafulvalene - TTF - pyridyl - cyclam -
electrochemical recognition.
