Methods, compositions, and systems for detecting explosives is disclosed and described. A sensor for detecting explosives can comprise a porous hydrophilic material modified with a series of π conjugated molecules with the general structure:
[EW]-[CS]-[PED]
wherein EW is an electron withdrawing group, CS is a conjugated system, and where PED is a pre-electron donating group. The porous hydrophilic material is capable of detecting hydrogen peroxide by reacting the aryl boronate group (or other Pre-ED groups) with the hydrogen peroxide to provide a fluorescent change.
本文公开和描述了一种检测爆炸物的方法、组合物和系统。用于检测爆炸物的传感器可以包括一种多孔亲水材料,该材料经过一系列π共轭分子的修饰,其一般结构为:[EW]-[CS]-[PED],其中EW是一个电子吸引基团,CS是一个共轭系统,PED是一个预电子给予基团。这种多孔亲水材料能够通过将芳基硼酸酯基团(或其他预电子给予基团)与过氧化氢反应来提供荧光变化,从而检测到过氧化氢。
