Dependence of the CS@Py response (R) under nitrogen, air, and oxygen for different solvents.

Solvent	R[a] N2	R[a] [O2]0.21 atm	R[a] [O2]1 atm	QO2 [%]
Hexane	0.70	2.19	6.83	91
Dichloromethane	0.59	0.97	2.49	81
Ethyl acetate	0.35	0.91	2.77	87
Tetrahydrofuran	0.52	1.53	3.88	87
Chloroform	0.82	1.39	2.75	76
Toluene	0.40	1.02	2.95	89
Dioxane	0.61	0.86	1.80	75

[a] R is the τ_CS/τ_d ratio. [b] Q_O2=(R_N2−R_O2)/R_N2×100; R_O2 at 1 atm.
