Abstract
빌리루빈의 경우와 같이 옥소디피로메텐도 자체증감작용으로 생긴 단일상태 산소와 반응하여 광분해 하였다. 단일상태 산소의 수명이 각각 다른 용매에서 시험한 결과, 수명이 더 긴 용매에서 옥소디피로메텐의 공산화반응이 빨랐으며, 단일상태 산소의 켄칭제가 존재하는데서는 광반응이 느렸다. 더우기, 증감제를 사용하지 않은 반응에서 생성물이 증감제를 사용한 반응에서 생성물과 같았다.

Oxodipyrromethene was degraded by a self-photosensitized reaction, similar to the degradation of bilirubin by other investigators. Photodegradation of oxodipyrromethene was faster in methanol-d4, in which the life time of singlet oxygen is longer, than in methanol. It was slower in a solvent which contained a singlet oxygen quencher. Moreover, the products from sensitized and unsensitized reactions are same.
