Tris(bipyridine)ruthenium(II) is known for its interesting photophysical properties including ground and excited state stability, long lived emission in the excited state and strong absorbance in the visible region. Because of this, ruthenium bipyridine complexes have long been investigated as potential solar energy collectors. We report on the synthesis, chemically-induced luminescence, and emission spectra of three Ru(bpy)2�-diketonates ([Ru(bpy)2(RCO-CH=C(O)R)]+ where R = CH3, CF3 or CH3/CF3. We are expecting to see a correlation between wavelengths of emission and the substituents on the �-diketonate ligands.
