  which involves the intermediacy of a diene cation radical generated by transfer of an electron from the adsorbed diene to a photogenerated hole localized at the surface of the excited TiO2 particle. Non-oxidative cleavage products are also observed, and the effect of the semiconductor surface in controlling reactivity of the photogenerated cation radical is discussed. The first examples of aromatization

  研究了悬浮在氧化CH 3 CN中的TiO 2粉末的长波长紫外线辐照引起的共轭二烯的非均相光化学氧化。在几乎所有情况下，都观察到由双键的氧化裂解产生的产物，与先前报道的单烯烃平行。提出了一种机制，该机制涉及通过将电子从吸附的二烯转移到位于激发的TiO 2表面上的光生空穴而产生的二烯阳离子自由基的中间体。粒子。还观察到非氧化裂解产物，并讨论了半导体表面在控制光生阳离子自由基反应性中的作用。提出了由辐射的半导体悬浮液介导的芳构化和Diels-Alder二聚化的第一个例子。
