本文研究了反式，反式－１，４－二苯基－１，３－丁二烯（ＤＰＢ）在沸石ＮａＺＳＭ－５中的光敏氧化反应．在溶液中９，１０－二氰基蒽（ＤＣＡ）敏化光氧化反应有两种机制：单重态氧机制和电子转移产生超氧负离子机制．我们把ＤＰＢ吸附在沸石ＺＳＭ－５孔道中，ＤＣＡ溶解于沸石外部溶剂季戊四醇三甲醚中，溶剂和敏化剂都不能进入沸石孔道．光照反应后，在沸石孔道中只得到ＤＰＢ的单重态氧的反应产物，没有电子转移的产物产生．反应产物产率为１００％．大大提高了反应的选择性
In this paper, the photooxidation of trans, trans 1,4-diphenyl-1,3-butadiene (DPB) in zeolite NaZSM-5 was studied. In solution, 9,10-dicyanoanthracene (DCA) sensitized photooxidation has two mechanisms: singlet oxygen mechanism and electron transfer to produce superoxide anion mechanism. We adsorbed DPB in the pores of zeolite ZSM-5. DCA was dissolved in pentaerythritol, an external solvent of zeolite. Neither solvent nor sensitizer entered the zeolite pores. After the photo-reaction, only the reaction product of singlet oxygen of DPB is obtained in the zeolite pore, and the product without electron transfer is produced. The yield of the reaction product was 100%. Greatly improving the selectivity of the reaction
