Singlet oxygen quantum yields QY1

Anthrone

Redmond, R.W.; Braslavsky, S.E.
Chem. Phys. Lett. 148(6): 523-9 (1988)

Sensitizer: Anthrone
Solvent: C₆H₆
Oxygen concentration: O₂

Quantum yield of formation = 0.25^T
Fraction of T₁ yielding singlet oxygen = 0.25

Experimental method: pulsed laser photolysis
Data type: luminescence intensity at end-of-pulse or under steady-state conditions

Reference sensitizer = Pz; rel. to phi_Delta(ref. sens.) = 0.83; used phi_T(S) = 1. Measured Proportion of T₁ quenched by O₂ = 1.
