This article comprehensively studies the benzene sulfur and selenium) (oxygen, nitrogen heterocyclic synthesis of tertiary aromatic amine and in ISO800 Gao Gan super intensifying application of emulsion. Organic sensitizing dye are discussed in detail in the sensitized emulsion two since the desensitization mechanism and the corresponding two kinds of sensitizing mechanism, combined with the current different super sensitizer used by foreign companies, this article puts forward the benzene sulfur and selenium) (oxygen, nitrogen heterocyclic super sensitizing effects of tertiary aromatic amine, and studies in detail its synthesis method, optimized the synthetic process conditions, the synthesis of 6 kinds of intermediates and 11 kinds of super sensitizer, and through the element analysis, infrared spectrum and nuclear magnetic resonance (NMR) spectrum instrument detection means to structure verification. Through the ESR (electron paramagnetic resonance) and photoelectron lifetime of spectral experiments verify the benzene sulfur and selenium) (oxygen, nitrogen heterocyclic super sensitizing effects of tertiary aromatic amine, verify the double electron super sensitizing mechanism at the same time. In ISO800 Gao Gan emulsion emulsion formulation was carried out in the experiment, testing the different concentrations of 11 kinds of super sensitizer in ISO800 Gao Gan the photographic properties of emulsion and film aging performance experiments, the experimental results show that benzene sulfur and selenium) (oxygen, nitrogen heterocyclic tertiary aromatic amine emulsion speed can be enhanced by 20-30%, have obvious super sensitizing effect, and has good stability in the film aging process.
