Specific quenching of the photoexcited state of tris(2,2′-bipyridine)ruthenium(II) by colloidal prussian blue
Abstract
Static quenching of the photoexcited state of the tris(2,2′-bipyridine(ruthenium(II) complex by colloidal prussian blue (PB) in water has been studied. The quenching behaviour has been analysed in terms of stepwise complex formation between Ru(bpy)2+3 and PB which obeys Poisson statistics. The binding of the Ru complex to the colloidal PB particle is discussed.
