fluorophores has been evaluated toward nitroaromatic compounds, including such well-known explosives, as 2,4-dinitroanisole, picric and styphnic acids, 1,3,5-triethoxy-2,4,6-trinitrobenzene, 2,4-dinitrotoluene, 2,4,6-trinitrotoluene, 2,4,6-triamino-1,3,5-trinitrobenzene and nitrobenzene. The detection limits for these fluorophores in relation to nitroaromatic compounds in acetonitrile solution proved to be in
摘要已经设计,合成和表征了带有嘧啶供体片段的基于嘧啶的新型荧光团。已评估了这些荧光团对硝基芳香族化合物的荧光行为,包括诸如2,4-二硝基苯甲醚,苦味和甲氧烷酸,1,3,5-三乙氧基-2,4,6-三硝基苯,2, 4-二硝基甲苯,2,4,6-三硝基甲苯,2,4,6-三氨基-1,3,5-三硝基苯和硝基苯。相对于乙腈溶液中的硝基芳香族化合物,这些荧光团的检测限证明为10 -1至10 -7 摩尔/升。基于这些荧光团的手持式嗅探器“ Nitroscan”(俄罗斯植物“ Promautomatika”)的传感器原型已经制造出来并用于应用,如可重复使用,可逆和灵敏的快速检测硝基苯和2,4,6-。气相中的三硝基甲苯浓度分别高达6和5 ppb。 图形概要
