Physical, spectroscopic, and biological properties of ruthenium and osmium photosensitizers bearing diversely substituted 4,4′-di(styryl)-2,2′-bipyridine ligands

Capitalising on the previous identification of a distyryl coordinated Ru(ii) polypyridine complex as a promising photosensitizer for photodynamic therapy, eight new complexes were synthesized by modifications of the ligands or by changing the metal coordinated. We report in this work the effects of these modifications on the physical, spectroscopic, and biological properties of the synthesized complexes. Subtle structural modifications of the distyryl ligand only had a moderate effect on the corresponding complexes' visible light absorption and singlet oxygen quantum yield. These modifications however had a significant effect on the lipophilicity, the cellular uptake and the phototoxicity of the complexes. Although the lipophilicity of the complexes had a somewhat expected effect on their cellular uptake, this last parameter could not be directly correlated to their phototoxicity, revealing other underlying phenomena. Overall, this work allowed identification of two promising ruthenium complexes as photosensitisers for photodynamic therapy and provides some guidance on how to design better photosensitizers.

Comparative chemistry of bipyrazyl and bipyridyl metal complexes: Spectroscopy, electrochemistry, and photoanation

The photoanation of the bipyrazyl complex Ru(bpz)3(PF6)2, in acetonitrile containing chloride ion, leads to the formation of cis-Ru(bpz)2(CH3CN)Cl+ (maximum quantum yield 0.37), cis-Ru(bpz)2Cl2 (maximum quantum yield 0.001), and an unidentified mono(bipyrazyl)ruthenium(II) derivative. The mechanism of this reaction is discussed. Reaction of M(CO)6 (M = W, Mo) with bipyrazyl yields M(CO)4bpz. The electronic, vibrational, and 1H NMR spectra and electrochemistry of these products were compared with those of their bipyridyl analogues. It is concluded that bipyrazyl is no better a π acceptor than bipyridyl because of weaker σ bonding leaving the metal ion more positvely charged.
