Tris(2,2′-bipyridine)ruthenium(II) (Ru(bpy)32+)-fluortetrasilicic mica (TSM)-poly(vinylpyrrolidone) (PVP) intercalation compounds were prepared, and the photoluminescent behavior of intercalated Ru(bpy)32+ was investigated. The luminescence maxima of intercalated Ru(bpy)32+ shifted gradually toward the blue with decreased loading of Ru(bpy)32+, reflecting the change in the polarity and/or rigidity of the microenvironment of Ru(bpy)32+, presumably caused by cointercalated PVP. Moreover, Ru(bpy)32+ self-quenching was suppressed even at its high concentration loading. It was supposed that cointercalated PVP prevented self-aggregation by surrounding Ru(bpy)32+ in close contact in the sterically limited interlayer spaces.
