Pt(II)(bpy)(N,S-aminoethanethiolate)^a1	3.2 ± 0.3	0.00
Pt(II)(bpy)(N, S(=O)-aminoethanesulfenate)^a2	0.25 ± 0.03	0.00
Pt(II)(bpy)(N,S(=O)2 - aminoethanesulfinate)^a3	0.098 ± 0.008	0.00
Pt(II)(bpy)(1,2-benzenditholate)^b4	4.8 ± 0.4	0.50 ± 0.05

In D₂O, average of 3-5 runs, error is one standard deviation

In CD₂Cl₂, average of 3-5 runs, error is one standard deviation

Determined at λ_exc. = 532 nm from the near-infrared ¹O₂ emission.
