Abstract

Luminescence quenching of tris(2,2'-bipyridine)ruthenium(II)-saponite film by sulfur dioxide is reported. The film was prepared by the ion exchange reactions of tris(2,2'-bipyridine)ruthenium(II) dichloride with Zn(II) exchanged saponite film. The change in the luminescence intensity was reversible upon the contact and the removal of sulfur dioxide, suggesting energy-transfer from tris(2,2'-bipyridine)ruthenium(II) in the saponite film to sulfur dioxide to deactivate the excited state of the dye.
