Intercalation of tris(2,2'-bipyridine)ruthenium(II) into a layered perovskite derived from aurivillius phase Bi2SrTa2O9
Intercalation of tris(2,2'-bipyridine)ruthenium(II), Ru(bpy)(3) (2+), into a layered perovskite derived from Aurivillius phase Bi2SrTa2O9 was successfully achieved by a guest ion-exchange method using n-C6H13NH3+-SrTa2O7 hybrid compound as an intermediate. X-ray diffraction analysis revealed that the structure of the perovskite-like slabs in Bi2SrTa2O9 was retained after the intercalation reactions. Ru(bpy)(3) (2+) shows pronounced spectral red shifts in both its absorption and emission spectra (relative to those in water) when it is incorporated into the perovskite-like slabs.
