説明
The Ru(II)–poly(4-vinylpyridine) complexes, [Ru(bpy)2(PVP)2]Cl2, and [Ru(bpy)2(PVP)(py)]Cl2 have been synthesized and compared spectroscopically with the monomeric [Ru(bpy)2(py)2]Cl2 complex, where py is pyridine, bpy is 2,2′-bipyridine, and PVP is poly(4-vinylpyridine). The polymeric Ru(II) complexes were synthesized by the substitution of Cl in Ru(bpy)2Cl2 for poly(4-vinylpyridine) in methanol. The six-coordinated polymeric Ru(II) complex, [Ru(bpy)2(PVP)2]Cl2, was insoluble in water due to an intermolecular ligand complex formation, while one substituted complex, [Ru(bpy)2(PVP)(py)]Cl2, was soluble in water. The absorption maximum of [Ru(bpy)2(PVP)(py)]Cl2 was red-shifted ca. 10 nm from that of [Ru(bpy)2(py)2]Cl2. Also, the red-shift was observed in the emission spectrum. The emission intensity of the polymeric Ru(II) complex was smaller than that of the monomeric one, whereas the emission lifetime was a little different. The difference in energy transfer processes for the above complexes is discussed.
