| 摘 要： | 本文研究了在二氟甲烷中9,10-二氢基蒽(DCA)敏化光氧化反,反-1,4-二苯基-1,3-丁二烯(DPB)反应中四氟硼酸四正丁基铵盐的作用,认为四极铵盐能促进激基复合物的解离,增加电荷分离,加速反应的进行并影响产物的分布。本文还讨论了盐效应对电子转移光化学反应中机理研究的作用及在合成应用中的可能性。

| Abstract: | R4NBF4 effects were studied in 9,10-dicyanoanthracene sensitized photooxidation of 1,4-diphenyl-l,3-butadiene in CH2Cl2.Because of the association of the dipolar salts to form qua-drupoles which can react with exciplex giving radical ions,the photooxidation was accelerated by addition of R4NBF4 and the product distribution was changed.The usage of salt effect in mechanism study and synthesis were discussed. |

| Keywords: | electron transfer salt effect photooxidation |
