摘要
本文以结晶紫、吖啶橙为光敏化剂，以Ｎ—对甲苯磺酰基－７－氮杂－双环［２．２．１］－２，５－庚二烯－２，３－二羧酸二甲酯（ＮＮＢＤ）为反应底物，测定了ＮＮＢＤ光敏异构化反应的转化率及量于产率。通过荧光谱和ＮＮＢＤ对敏化剂的荧光猝灭试验，根据ｗｅｌｌｅｒ电子转移理论对ＮＮＢＤ的光敏异构化机理进行了探讨。
The conversion yield and quantum yield of photoinduced isomerization of dimethy1 N-(p-toluenesulfony1) 7 aza bicyclo[2.2.1]2,5 heptadiene 2,3 dicarboxylate(NNBD),with crystal violet and acridine orange as sensitizers, had ben measured. Based on the fluorescence spec tra and fluorescence quenching of the photasensitizers by NNBD,the reaction mechanism of electron transfer ismerization was tentatively proposed.
