k = 1.5 × 10⁸(L mol^-1 s^-1)

Experimental method: Photolysis
Analytical method: vis-UV emission
Data type: Derived from steady state measurements using indicator

Photosensitizer = Indicator = Rubrene; used solvent k_d = 1.4 × 10³ s^-1; k for indicator = 7 × 10⁷ L/(mol·s); Measured k_A/(k_A¢[A¢] + k_d) = 8.2 × 10⁴ L mol^-1 at [A¢] = 5 × 10^-6 mol L^-1.
