本工作采用瞬态和稳态的方法对带不同取代基碘鎓盐的直接光解和敏化光解问题进行了研究,存两种光解过程中,电子转移均起到重要作用。在直接光解反应中,由于开始时生成的带不同取代基的苯衍生物在进一步反应中起到重要作用,因此它们的光解效率如下:3>2≥1,在敏化光解反应中,由于2—氯代硫杂蒽酮(CTX)作为电子给体参与其中。因此敏化光解效率和所研究鎓盐的得电子能力有关,其次序如下:l>2≥3。 In this work, we studied the photodegradation and sensitized photolysis of iodonium salts with different substituents using transient and steady-state methods. Both photolysis processes play an important role in the electron transfer. In the direct photolysis reaction, the benzene derivatives with different substituents generated at the beginning play an important role in the further reaction, so their photolytic efficiency is as follows: 3> 2 ≧ 1, in the sensitizing photolysis reaction , Since 2-chloro thioxanthone (CTX) is involved as an electron donor. Therefore, sensitized photolysis efficiency and on the electronic power of the onium salt, the order is as follows: l> 2 ≥ 3.
