It is found that singlet oxygen (¹O₂) can react with benzobisthiazole-based photocatalysts via [4+2] cycloaddition, leading to the formation of endoperoxide intermediate species, which promotes the separation of charge carriers and reduces the barrier for hydrogen peroxide (H₂O₂) production. The H₂O₂ production rate of the catalyst is as high as 7274 μmol g⁻¹ h⁻¹ in pure water in air.

通过产生和转化单线态氧促进噻唑基共轭聚合物太阳能驱动的过氧化氢生产

研究发现，单线态氧（¹ O ₂）可以与苯并双噻唑基光催化剂通过[4+2]环加成反应，形成内过氧化物中间体，从而促进电荷载流子的分离并降低过氧化氢的势垒（ H ₂ O ₂ )的产生。该催化剂在空气中的纯水中H ₂ O ₂产率高达7274μmol g ^-1 h ^{-1 。}
