| 摘 要： | 本工作合成了硫代α-萘甲酸-s-苯酯和硫代苯甲酸-s-苯并噻唑酯,对其光化学和光物理行为进行了研究。由于萘基和苯并噻唑基的引入,有效地增加了该类化合物的最大吸收光谱范围,并在受光激发后,可观察到有荧光发射。工作中发现,硫代α-萘甲酸-s-苯酯荧光发射强度会随光照时间的增加而加强,这是因该化合物光解时生成了有高荧光量子产率的α,α'-联萘;但在硫代苯甲酸-s-苯并噻唑酯的光解中观察不到上述现象,文章对所得结果进行了讨论。

| Abstract: | In this work sphenyl 1-thionapthoate and 2-benzoylthiobenzothiazole were synthesized and their pbotochemical and photophysical behavior were studied.Due to introductionof naphthyl and benzothiazolyl group,the absorption range of these compounds have beenefficiently broadened.It was discovered in this work that the intensity of sphenyl 1-thion-aphthoate increased with time interval of irradiation,which was because of production of α,α'-binaphthyl with high fluorescence quantum yield.However,the phenomenon could notbe observed in photolysis of 2-benzoylthiobenzothiazole.Cage effect and external magneticfield effect also were discussed in this paper. |
