【摘要】 设计合成了一个新的双1,8-萘酰亚胺衍生物（Bis-Nph）,并通过核磁共振波谱和高分辨质谱鉴定了其结构.Bis-Nph呈现出典型的分子内电荷转移（ICT）和聚集诱导增强发射（AIEE）.该化合物可以作为荧光探针检测水溶液中的苦味酸（2,4,6-三硝基苯酚,TNP）,检出限为5.8×10^-7mol/L.作用机制为TNP的质子转移到Bis-Nph,有效地阻断了其ICT发射,使荧光发生显著猝灭.另外,Bis-Nph的细胞毒性较低,可做成试纸进行TNP的快速检测.更多还原

【Abstract】 A novel bis-naphthalimide derivative（Bis-Nph）was designed,synthesized and characterized by nuclear magnetic resonance spectroscopy（NMR）and high resolution mass spectrometry（HRMS）.Compound Bis-Nph presented typical intramolecular charge transfer（ICT）emission and aggregation-induced enhanced emission（AIEE）.It could be used as a fluorescent probe to detect 2,4,6-trinitrophenol（TNP）in aqueous solution,the calculated limit of detection is 5.8×10^-7mol/L.The mechanism for sensing TNP was investigated using¹H NMR.The proton transfers from TNP to Bis-Nph and blocks the ICT emission,and causes the fluorescence to be quenched remarkably.Further,Bis-Nph showed low cytotoxicity and could be made into test strips for rapid TNP detection.更多还原
