Abstract

Tetraarylporphyrin ruthenium complexes [Ru(L)(aryl4Por)] (L = CO or PF3; aryl = mesityl or 10-R′-bis-methano-octahydroanthracene-9-yl with R′ = H, CF3, OCH3 or CH3) show a rich electrochemistry with at least five different stable oxidation states (including the parent state). The overall character of the redox behaviour is porphyrin-centred. However detailed spectroelectrochemical investigations using IR, UV/Vis/NIR and EPR spectroscopy (X- and K band) gave clear indication for ruthenium contributions.
