Electrochemistry of cis-diaquo ruthenium(II) complexes with substituted 2,2'-bipyridine ligands in a non-coordinating solvent. Application to the elaboration of corresponding functionalized polypyrrole films.
New cis-diaquo Ru(II) complexes [Ru(L)2(OH2)2]2+ with L = 2,2'-bipyridine substituted by ramified or long chain alkyl groups were prepd. to study their electrochem. behavior in a noncoordinating solvent like CH2Cl2. Slow mono and bis-aquo substitutions by counteranions (Y-) from the electrolyte are obsd. leading to [Ru(L)2(OH2)(Y)]+ and [Ru(L)2(Y)2]. The kinetic of the process is time dependent on the electrolyte used (TBAP or TBATF). By using a 2,2'-bipyridine ligand functionalized by a pyrrole group (L1), films of poly[Ru(L1)2(OH2)2]2+, poly[Ru(L1)2(OH3)(Y)]+ and poly[Ru(L1)2(Y)2] are readily obtained by anodic polymn. These modified electrodes were electrochem. and spectrochem. characterized and the electrocatalytical properties of the C/poly[Ru(L1)2(OH2)2]2+ modified electrode were examd. [on SciFinder(R)]
