Efficient near IR sensitization of nanocrystalline TiO2 films by ruthenium phthalocyanines

Bis(3,4-dicarboxypyridine)(1,4,8,11,15,18,22,25-octamethyl- phthalocyaninato)ruthenium(II) (JM3306) anchored to nanocrystalline TiO2 films through the axial pyridine 3,4-dicarboxylic acid ligands is an efficient near IR sensitizer for photovoltaic injection cells based on nanocrystalline TiO2 films.
