摘　　要：设计并合成了一种新型四苯乙烯衍生物(TPE-H),该衍生物在THF/H_(2)O(0.5/9.5,体积比)溶液介质中显示出明亮的红色聚集诱导发射(AIE)特性。TPE-H通过荧光“开-关”策略选择性地鉴别Pd^(2+)。该传感器具有出色的选择性和灵敏度,并在很宽的pH范围(4~10)内显示出出色的稳定性。对Pd^(2+)检测的详细研究表明,Pd^(2+)的检出限为9.81×10^(-8)mol/L。通过核磁共振氢谱、傅里叶红外光谱和质谱等测试确认了传感机理。在传感试纸和真实水样测试中,TPE-H对Pd^(2+)具有良好的传感效果,误差较小。该研究不仅报道了一种有效的Pd^(2+)荧光传感器,而且为在复杂环境中原位和实时传感Pd^(2+)提出良好的应用前景。A novel tetraphenylethylene derivative(TPE-H)was designed and synthesized,which exhibited bright red aggregation induced emission(AIE)characteristics in THF/H_(2)O(0.5/9.5,volume ratio)solution medium.TPE-H selectively identified Pd^(2+)through a fluorescence“on-off”strategy.This sensor had excellent selectivity and sensitivity,and exhibited excellent stability over a wide pH range(4-10).Detailed research on Pd^(2+)detection showed that the detection limit for Pd^(2+)was 9.81×10^(-8)mol/L.The sensing mechanism was confirmed through 1H NMR,Fourier transform infrared spectroscopy spectroscopy and mass spectroscopy.In the sensing test paper and real water sample testing,TPE-H had good sensing effect on Pd^(2+)with small errors.This study not only reported an effective Pd^(2+)fluorescence sensor,but also proposed good application prospects for in-situ and real-time sensing of Pd^(2+)in complex environments.
