Synthesis and photochemical properties of a new substituted phenol covalently linked to ruthenium (II) tris-bipyridine containing four ester groups as sensitizer

• As photosensitizer for solar cell, a new ruthenium (II) complex with four ester groups had been synthesized, in which a phenol substituted by {[(2-hydroxy-5-tert-butylbenzyl)(pyridyl-2-methyl)amino]methyl} is covalently linked to ruthenium (II) tris-bipyridine. The structures of the new compounds were confirmed by NMR and ESI-MS spectra. The electrochemical and photochemical properties were also studied.
