Synthesis and spectroscopic properties of Tris(2,2'-bipyridine)ruthenium(II) in zeolite Y
Tris(2,2'-bipyridine)ruthenium(II) complexes have been synthesized within the large cavities of dehydrated Y-type zeolites by allowing bipyridine to react with a Ru(NH/sub 3/)/sub 6/-Y form of the zeolite. The resulting Ru(bpy)/sub 3//sup 2 +/ complexes are characterized by absorption and emission bands similar to those found in aqueous solutions. The relatively high concentration of the Ru(bpy)/sub 3//sup 2 +/ complexes resulted in concentration quenching. As the addition of water to the samples approached saturation, the luminescence was quenched; however, small amounts of water increased the luminescence in a sample which contained 2.8 complexes per unit cell. Emission was also quenched upon addition of O/sub 2/ to the zeolite, with the effect being more pronounced in samples having a smaller concentration of complexes. 30 references, 6 figures, 1 table.
