Abstract
Fate pathway of cis-Ru(dcbpy)2(NCS)2; dcbpy = 2,2′-bipyridyl-4,4′-dicarboxylic acid, attached to the anatase titanium dioxide surface was investigated from time-course of UV-vis absorption spectra as well as FT-IR spectra under photo-irradiation (AM1.5) or under dark at different temperatures (−18°C, 25°C, and 100°C). Series transformation reactions of two NCS ligands to CN, one by one, were evident from those spectral changes and characteristic FT-IR vibrational frequencies.
