Abstract

Two trinuclear ruthenium complexes [{TolylTerpyRu}3(L3A)]·(PF6)9 and [{TolylTerpyRu}3(L3B)]·(PF6)9 containing the star-shaped ligands 1,3,5-tris{[4′-(2,2′:6′,2″-terpyridinyl)-1-pyridiniumyl]methylphenyl}benzene (L3A) and 2,4,6-tris{[4′-(2,2′:6′,2″-terpyridinyl)-1-pyridiniumyl]methyl}mesitylene (L3B), respectively, have been synthesized and characterized using electrospray ionization mass spectrometry, UV-Vis spectroscopy, 1H and 13C NMR spectroscopy. These cationic ligands have been synthesized using a 1,3,5-triphenylbenzene or a mesitylene core and the N-alkylation of the 4′-pyridyl group of 4′-(4-pyridyl)-2,2′:6′,2″-terpyridine (terpy,py). The electrochemical properties of the two trinuclear ruthenium complexes have been compared to analogous dinuclear and mononuclear ruthenium complexes.
