Reactivity of a pyridinium-substituted dimethyldihydropyrene switch under aerobic conditions: self-sensitized photo-oxygenation and thermal release of singlet oxygen.

The behavior of a pyridinium-substituted dimethyldihydropyrene photo-switch under aerobic conditions was investigated. During irradn. with red light ($łambda$ ≥ 630 nm), this compd. plays the role of oxygen sensitizer and is quant. converted into an endoperoxide deriv. The photo-produced endoperoxide then thermally releases singlet oxygen to regenerate the starting compd. [on SciFinder(R)]
