Electron-transfer quenching of tris(2,2-bipyridine)ruthenium(II) by methylviologen in an aqueous suspension of clay in the presence of poly(vinylpyrrolidone) was investigated. The quenching behavior of the excited tris(2,2-bipyridine)ruthenium(II) on clay by the coadsorbed methylviologen indicated the homogeneous distribution of the adsorbed dyes. The quenching rate was high when the clay with larger particle size was used as the host. The adsorption of poly(vinylpyrrolidone) on clay resulted in the coadsorption of the tris(2,2-bipyridine)ruthenium(II) and methylviologen without segregation.
