Ru(bpy)32+

excited state quenched by 4,4'-Dimethyl-bpyH22+
Krishnan, C.V.; Creutz, C.; Schwarz, H.A.; Sutin, N.
J. Am. Chem. Soc. 105: 5617-23 (1983)

Ru(bpy)32+ quenched by 4,4'-Dimethyl-bpyH22+ at conc. (5-50) x 10–4 mol L–1
Solvent : H2O, 25ºC, ionic strength 0.5 (NaHSO4, Na2SO4)

kq = 1.5 x 109(L mol–1 s–1)

Mechanism: oxidative electron transfer
Experimental methods: steady state irradiation, luminescence
Lifetime in the absence of quencher, air free = 0.60 micro sec. (766404)
Comments: kq from pH dependence of KSV
