基于吖啶酮衍生物新型传感器的设计合成及性能研究

Synthesis and Performance of Novel Chemosensor Based on Acridone Derivatives

以吖啶酮为荧光团,引入离子识别基团设计合成了一种新型化学传感器ANSA。该化合物的结构通过氢谱、碳谱以及高分辨质谱进行确认。对传感器的性能研究试验表明,该传感器在水溶液中对Cu^(2+)的识别具有专一性、强抗干扰性,pH 7左右时对Cu^(2+)的识别作用最强。Job's plot曲线表明,Cu^(2+)与传感器配位比为1∶2,该传感器对多种形式的铜源都具有较好的识别作用。

A novel acridone chemosensor ANSA,which introduced an ion recognition group,was synthesized.The structures of compounds were confirmed by ^1HNMR,^13CNMR,HRMS.When the water buffer was chosen as a test solvent,ANSA had an excellent special identification capacity for Cu^2＋ and a strong anti-interference ability.The ability of recognition was strongest when pH of the buffer was about 7.The complex of Cu^2＋ and ANSA was 1∶2.The chemosensor was the same recognition ability to Cu^2＋ when the copper salt was different.
