Sensitizer: Imidazole, 4,5-diphenyl-2-[(2-carboxy-5-methylphenyl)azo]-, chromium(III) salt (Cr(III) Dye II)
Solvent: DMF
Oxygen concentration: air^a

Experimental method: continuous photolysis
Data type: substrate consumption under steady-state conditions

Reference sensitizer = Zn(II) Dye II; Singlet oxygen acceptor = DPBF; meas. phi_Delta(S)/phi_Delta(ref. sens.) = 14.

^a Oxygen concentration not given; assumed to be air saturated.
