Abstract

The main photodegradation mechanisms of pyrromethene 567 are discussed, and the quantum efficiency of self-sensitized photo-oxidation, the predominant mechanism, was found to be 0.5% in aerated benzene-d₆. Other degradation mechanisms do exist, but the high photostability of the dye in solid host media possibly implies that they are all diffusion controlled. Solid-state dye lasers based on pyrromethene 567 doped poly(methyl methacrylate) with an added singlet oxygen quencher 1,4-diazobicyclo [2,2,2] octane (DABCO) showed a lifetime of 550,000 pulses. A triplet quencher, perylene, provided no improvement. Singlet oxygen quenching is effective in the solid-state whereas triplet quenching is not, presumably due to the slower diffusion rate of dye molecules compared with oxygen.
