Abstract

Four new trinuclear complexes were successfully synthesized through the dative binding of one unit of (bpy)2RuII and one unit of (phen)2RuII to the periphery of octakis(benzylthio)tetraazaporphyrinmagnesium(II) [Mg(OBTTAP)] and octakis(methylthio)tetraazaporphyrinmagnesium(II) ([Mg(OMTTAP)]). Spectroscopic techniques were used to perform an extensive characterization of the complexes, including an analysis of their fluorescence excitation/emission spectra and redox behaviours. Effective electronic interaction between the peripheral (bpy)2RuII/(phen)2RuII and [Mg(OBTTAP)] units is evidenced by the presence of these complexes. In cyclic voltammetry, the oxidation waves were slightly altered to a higher positive potential upon attaching a second Ru(II) unit in complexes 6, 7, 8 and 9.
