Titanium oxide/bis[(4,4′‐carboxy‐2,2′‐bipyridine)(thiocyanato)]ruthenium ( cis ‐(NCS) 2 RuL 2 ) nanocomposites were prepared by the self‐assembly method. In this system, their interfacially local structures were probed by x‐ray absorption spectroscopy (XAS) and the Ti–O interatomic distance and the coordination number of the O atoms around the Ti central atoms were extracted. Compared with TiO 2 nanoparticles, the Ti local structure in the nanocomposite was changed, which is responsible for binding cis ‐(NCS) 2 RuL 2 to the surface of TiO 2 nanoparticles.
