detection became more and more important. Boron ester or acid is considered to be a suitable functional group for the detection of hydrogen peroxide due to its reliable reactive activity. Its only drawback lies on its slow degradation velocity. In this work, we try to introduce some functional group to make the boron ester to be easily oxidized by H2O2. Herein, 4-(phenyl(4-(4,4,5,5-tetramethyl-1,3,2-dio
有机薄膜荧光探针的优点是不污染分析物,响应速度快,在爆炸物检测中引起了广泛的关注。与硝基炸药不同,基于过氧化物的炸药由于紫外线吸收差且缺乏芳环而几乎无法被检测到。作为过氧化物基炸药的标志性化合物,H 2 O 2蒸气检测变得越来越重要。硼酸酯或硼酸由于其可靠的反应活性,被认为是用于检测过氧化氢的合适的官能团。其唯一的缺点在于其缓慢的降解速度。在这项工作中,我们尝试引入一些官能团以使硼酸酯易于被H 2 O 2氧化。在此,合成了4-(苯基(4-(4,4,5,5-四甲基-1,3,2-二氧杂硼硼烷-2-基)苯基)氨基)苯甲醛(OTB),并合成了其亚胺衍生物OTBXAs。只需将OTB薄膜置于不同的伯胺蒸气中即可轻松获得。与OTB相比,OTBXA在H 2 O 2蒸气中显示出快速的脱硼速度。(E)-N-苯基-4-((丙基亚氨基)甲基)-N-(4-(4,4,5,5-四甲基-1,3,2-二氧杂硼烷-2-基)的
