Abstract
Reaction of 2,2′:4′,4″-terpyridine or 4-(4-pyridyl)-2,2′:4′,4″-terpyridine with [Ru(bipy)2Cl2](bipy = 2,2′-bipyridine), and of 4-(p-methoxyphenyl)-2,2′-bipyridine with [Ru(bipy)2Cl2] followed by demethylation of the anisole with BBr3, yields derivatives of Ru(bipy)3 2+ which contain externally directed pendant pyridyl or phenol groups capable of ligation to other metals. These complexes are proposed as ‘building blocks’ for photoactive polynuclear complexes containing the Ru(bipy)3 2+ chromophore. Methylation of the pendant pyridyl rings with methyl iodide generates electron-accepting groups covalently attached to the Ru(bipy)3 2+ core.Keywords
