The Synthesis of Phenothiazine Derivatives with Mechanofluorochromism Property and the Fluorescence Detection for 2, 4, 6-trinitrophenol

  • 摘要: 设计合成了2种具有明显聚集诱导发光(AIE)特性的吩噻嗪衍生物(SPA和SPN).荧光光谱研究表明, 这2种化合物在水溶液中能够特异性地识别2, 4, 6-三硝基苯酚(TNP), 其中SPA荧光检测TNP的猝灭率为89.1%, 猝灭常数Ksv为3.18×104 L/mol, 检出限为8.62×10-7 mol/L; SPN荧光检测TNP的猝灭率为90.4%, 猝灭常数Ksv为4.43×104 L/mol, 检出限为5.00×10-7 mol/L, 有望作为荧光探针特异性识别TNP.而且SPA分子具有可逆的力致荧光变色特性, 在紫外灯下发出蓝色荧光, 研磨后变为浅黄色, 有望被用于防伪材料或者可视化压力传感器领域.
