Abstract
Ruthenium(II) surface active complexes based on a tpySH ligand have been prepared and characterised, (1) [Ru(tpyada)(tpySH)](PF6)(2), (2) [Ru( biptpy)(tpySH)](PF6)(2) and (3) [Ru(pm-beta-CD( ttp))( tpySH)](PF6)(2). The complexes bear a surface active thiol group and a recognition unit which is either a beta-cyclodextrin or a hydrophobic tail (adamantyl- or biphenyl) in order to utilise cyclodextrin recognition for the formation of supramolecular wires using bottom up approaches. Monolayers of [Ru(tpyada)( tpySH)](PF6)(2) on ITO surfaces are studied by electrochemical techniques. Detailed NMR analysis of tpySH reveals the presence of two tautomers, an "NH" and an "SH" form. The X-ray crystal structure of the oxidised form of the ligand tpySStpy is reported. A new ligand tpySCH(2)Stpy is prepared and its dinuclear Ru(II) complexes are reported, (4) [(ttp) Ru(tpySCH(2) Stpy) Ru(ttp)](+)2, (5) [(biptpy) Ru(tpySCH(2)Stpy) Ru (bitpy)](+)2, (6) [(pm-beta-CD(ttp)) Ru(tpySCH(2) Stpy) Ru(pm-beta-CD( ttp))](+2). The complexes show characteristic red 3 MLCT luminescence which is much stronger than their analogous mononuclear counterparts.
