摘要:The complexes [cis-(RuL)-L-II'(2)(SCN)(2) and cis-(RuLL)-L-II'(SCN)(2)] (L = 4,4'-bis(ethoxycarbonyl)-2,2'-bipyridine, L'=2,2'-bpy-4,4'-CONH-L-tyrosine ethyl ester) are prepared and characterized. Two or four tyrosine ethyl ester groups are covalently linked to a ruthenium polypyridyl photosensitizer as electron donor. Upon light excitation, intermolecular electron transfer from the excited ruthenium(II) to MV2+ occurs, followed by intramolecular electron transfer from tyrosine moieties to Ru(III) with a rate constant of k(f) > 1 x 10(8)s(-1) (tau(f) < 10 ns).
