比尔(Birr)发现的稳定剂四氮茚,如4-羟基-6-甲基-1,3,3a,7-四氮茚,至今仍是最好的稳定剂之一。比尔还提出稳定机理,他认为,四氮茚只有未吸附于乳剂颗粒才能产生稳定效应。许多研究者研究过部分四氮茚的性能和照相效应。Evva和Kiss曾报导过四氮茚的氧化电势的重要性。在他们研究的基础上,本文作者对化合物(1)及其衍生物的分子、电子结构与照相性能之间的关系作了研究,并阐明:如其分子中没有
The tetrazolindane stabilizer found by Birr, such as 4-hydroxy-6-methyl-1,3,3a, 7-tetraazaindene, is still one of the best stabilizers to date. Bill also proposed a stabilizing mechanism, in his opinion, tetrazolizine only in the emulsion particles to produce a stable effect. Many investigators have studied the performance and photographic effects of partial tetrazolizines. Evva and Kiss have reported the importance of the oxidation potential of tetrazolizine. On the basis of their research, the authors studied the relationship between the molecular, electronic structure and photographic properties of compound (1) and its derivatives and clarified that if no
