摘　　要：以8-羟基-9-甲酰基久洛尼定和2-胺基-1,3-丙二醇缩合反应得到新型久洛尼定衍生物L,其结构经1H NMR,13C NM R,FT-IR,HRMS,元素分析及单晶XRD进行了表征。通过紫外-可见光谱法研究了目标物L在纯水溶液中与阴离子的识别特性。在纯水环境下,目标物L作为探针可对酸性较强的HSO4-具有特异选择性识别。此外,通过紫外-可见光谱滴定实验和1H NMR滴定实验对其与HSO4-离子的可能识别机制进行了初步验证。A novel fluorescent probe for HSO4- was synthesized by a facile one-step coupling of 8-hydroxy- julolidine-9-carboxaldehyde with 2-amino-1,3-propanediol, and then characterized by^1 H NMR, ^13 C NMR, FT- IR, HRMS, elemental analysis and single-crystal XRD techniques. The recognition properties of the probe L towards anion ions were investigated in a fully aqueous environment by ultraviolet spectrophotometry. The results showed that the probe L exhibited high selective recognition of HSO4 in fully aqueous solution. In addition, the proposed recognition mechanism and the 1 ： 3 stoichiometric structure between L with HSO4 were adequately supported by UV-Vis absorption titration andlH NMR study.
