Direct Ion Exchange of Tris(2,2-bipyridine)ruthenium(ll) into an a-Zirconium Phosphate Framework

The first direct ion exchange of a luminescent metal complex into an (alpha)-zirconium phosphate framework has been accomplished. A hydrated form of (alpha)-ZrP, with an expanded 10.3 A interlayer distance, has been used for the intercalation of Ru(bpy)3 resulting in further expansion to 15.2 A. The Ru(bpy)3 luminescence band is slightly blue-shifted. High Ru(bpy)3 loadings lead to luminescence self-quenching.
