The quenching of the [Ru(bipy)3]2+ by Cu2L2+ was studied and the data were plotted with the Stern-Volmer equation. The plot showed a break and was divided into 2 regions, <0.5 and >0.5 Cu2L2+: [Ru(bipy)3]2+ molar ratio. Quenching above the 0.5 Cu2L2+: [Ru(bipy)3]2+ molar ratio was slower (330 x 10-6 M-1s-1) than the quenching rate reaction below 0.5 ratio (387 x 10-6 M-1s-1).
With Cu2L2+ being a dimeric complex the …
