DOCUMENT TYPE: Journal CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) Section cross-reference(s): 72, 74 The new dye complex bis[4,4'-di(2-(3-methoxyphenyl)ethenyl)-2,2'-bipyridine][4,4'-dicarboxy-2 ,2'-bipyridine]ruthenium(II) dihexafluorophosphate (1) was prepd., characterized by absorption spectroscopy and adsorbed onto nanocryst. TiO2 electrodes. The resulting system was studied by absorption spectroscopy, electrochem. and photoelectrochem. and the results were compared to those for a ref.In this article, certain chemicals are used. One of their cas registry numbers is 349545-75-1 system with bis[2,2'-bipyridine][4,4'-dicarboxy-2,2'-bipyridine]ruthenium(II) (2). The system with 1 displays a broader and red shifted UV-visible absorption compared to that with 2. Also, the system with 1 is less sensitive towards the water content in the electrolyte, and an adsorbed monolayer of 1 remains on the electrode surface after days even in aq. NaOH (0.1M), while 2 desorbs immediately. .
