摘 要:采用乌尔曼反应、酸催化环化、N-烷基化和硫代化四步反应路线合成了5种不同结构的N-取代硫代吖啶酮,利用IR和MS分析手段表征了其结构,UV分光光度计的测定结果表明5种硫代吖啶酮在可见光区都有较强的吸收。其中N-丙基硫代吖啶酮的吸收波长为490nm,与氩离子激光的主发射波长相匹配。由硫代吖啶酮、二苯基碘鎓盐和活化剂组成的共引发体系使光聚合涂层的感度大大提高。N-substituded thioacridones with five different structures were synthesized via a route involving Ull-man reaction, cyclization, N-alkylation and sulfurization. The structures of each thioacridone were identified with IR and MS. The results from UV-spectrophotometry show that the five N-alkythioacridones all have stronger absorption in the visible light region. The peak absorption wavelength for N-propyl thioacridone is 490 nm and matchs with the emission of Argon-ion laser. It is found that the sensitivity of the photosensitive system with N-alkylthioacridone is improved strongly by further addition of diphenyl iodonium salt and activator.
