摘 要: | 以三苯胺为起始原料,经过酰基化、氧化缩合、亲核取代和季铵化等系列反应得到了荧光单体FM;荧光单体FM在硫代硫酸铵的作用下与丙烯酸(AA)、2-丙烯酰胺-2-甲基丙基磺酸(AMPS)单体发生自由基聚合,得到FM-AA-AMPS三元荧光共聚物潜指纹显现剂LF-1,其对潜指纹具有良好的吸附性能,在350 nm~500 nm范围内都能表现出良好的荧光效果。

Abstract: | The fluorescent monomer TM was prepared by triphenylamine through the reaction of acylation, oxidative dimerizations, nucleophilic substitution and quaternization. The fluorescence monomers (FM) were polymerized with acrylic acid ( AA), 2 - acrylamide - 2 - methyl propane sulfonie acid (AMPS) in water solution which triggered by ammonium persulfate. The polymer FM - AA - AMPS ( LF - 1 ) could recognize the latent fingerprints well under the excited excitation wavelength of 350- 500 nm. |
