Degradation of 4,6-dimethyldibenzothiophene (DMDBT), persistent sulfur contaminant in fuel oils has been achieved in non-polar phase by laser-irradiating DMDBT alone and in the presence of hydrogen peroxide and molecular oxygen. The most efficient degradation in the presence of molecular oxygen is judged to be the first example of self-sensitized photo-oxygenation of thiophenes, in which DMDBT sequentially acts as 1O2 sensitizer and reactant.
通过单独激光照射4,6-二甲基二苯并噻吩（DMDBT）以及在过氧化氢和分子氧存在的情况下，已实现了燃料油中持久性硫污染物4,6-二甲基二苯并噻吩（DMDBT）在非极性相中的降解。在分子氧存在下最有效的降解被判定为噻吩自敏化光氧化的首个实例，其中DMDBT依次充当单线态氧敏化剂和反应物。
