Preparation and Sensing Performance of Fluorescent Sensors Based on 4-NP and PA

4-硝基苯酚(4-NP)以及2,4,6-三硝基苯酚/苦味酸(PA)作为两种常见的硝基芳香烃(NACs)，被广泛应用于炸药制备、化工原料以及有机合成等领域。尽管应用广泛，但NACs具有较强的环境毒性和生物毒性，对人体健康有显著危害，所以设计一种灵敏度高、快速响应以及便携性好的发光传感器用于检测NACs就显得尤为重要。因此，本文选择一种具有较强蓝绿色发光的杂金属化合物，将其制备为PMMA杂化薄膜，用于特异性检测4-NP以及PA。4-Nitrophenol (4-NP) and 2,4,6-trinitrophenol/picric acid (PA), as two common nitroaromatic compounds (NACs), are widely used in fields such as explosive manufacturing, chemical raw materials, and organic synthesis. Despite their extensive applications, NACs exhibit strong environmental and biological toxicity, posing significant hazards to human health. Therefore, designing a highly sensitive, rapid-response, and portable luminescent sensor for detecting NACs is of great importance. In this study, a heterometallic compound with strong blue-green emission was selected and fabricated into a PMMA hybrid film for the specific detection of 4-NP and PA.
