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。
With acridone as a fluorophore, the introduction of ion recognition groups designed and synthesized a new type of chemical sensor ANSA. The structure of this compound was confirmed by hydrogen spectrum, carbon spectrum and high-resolution mass spectrum. Experimental research on the performance of the sensor shows that the sensor has unique specificity and strong anti-interference ability in the recognition of Cu 2+ in aqueous solution, and has the strongest recognition effect on Cu 2+ at pH 7 or so. Job’s plot shows that the coordination ratio between Cu 2+ and sensor is 1: 2. The sensor has a good recognition of various copper sources.
