本文对硫代苯甲酸-S-苯酯类化合物的敏化光解反应进行了研究,以图扩大其光谱响应范围.工作表明硫代苯甲酸-S-苯酯能与芘、(艹北)等敏化剂发生电子转移反应,并进而促使硫代苯甲酸-S-苯酯分子裂解,产生各种分解产物;气相色谱-质谱联用仪分析结果表明,敏化光解产物主要为苯甲醛和二苯基二疏醚,在此基础上对标题化合物敏化光解的机制提出了看法.此外,从该光敏体系能引发甲基丙烯酸甲酯聚合进一步表明,硫代苯甲酸-S-苯酯能与适宜的电子给体组成光敏引发体系,使该体系的光敏引发可用波长扩展到400nm以上.
In this paper, the sensitized photolysis reaction of S-phenyl thiobenzoate compounds was studied in order to enlarge its spectral response range.The work showed that S-phenyl thiobenzoate could react with pyrene, And other sensitizers electron transfer reaction, which in turn led to S-phenyl thiobenzoate molecule cleavage, resulting in a variety of decomposition products; gas chromatography-mass spectrometry analysis showed that sensitized photolysis products mainly benzaldehyde And diphenyl dithioether, on the basis of which, the mechanism of the sensitized photolysis of the title compound was put forward.In addition, the polymerization of methyl methacrylate can be induced from this photosensitive system further shows that the thiobenzoic acid-S-benzene The ester can form a photoinitiator system with suitable electron donors to make the photoinitiator of this system extend the available wavelength to over 400nm.
