Synthesis and Photochemical Properties of a New Substituted Phenol Covalently Linked to Ruthenium (Ⅱ) Tris-bipyridine Containing Four Ester Groups as Sensitizer

摘要

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.
