设计合成一种新型罗丹明类探针L,并研究了其光谱性质.实验结果表明,L在甲醇/水[V:V=8:2,c(Tris)=10 mmol/L,pH=7.2]体系中对三价金属离子(Cr3+、Fe3+、Al3+)具有荧光增强性响应,很好的选择性和较高的灵敏度,不受其它二价及一价金属离子的影响,抗干扰能力强.探针L对Cr3+、Fe3+、Al3+的紫荧光检测限分别为2.1×10-4、2.3×10-4和4.4×10-4 mol/L,表明其在各种水体样品中对三价金属离子的检测具有潜在的应用价值.

A novel rhodamine-based probe L was synthesized and characterized. The results showed that probe L acted as a fluorescent enhancement probe for Cr3+, Fe3+ and Al3+ recognition in CH3OH/H2O (V:V=8:2, c(Tris)=10 mmol/L, pH=7.2). L is highly selective to trivalent ions Cr3+, Fe3+ and Al3+ over other monovalent or divalent ions. Detection limits of probe L for Cr3+, Fe3+ and Al3+ are 2.1×10-4, 2.3×10-4 and 4.4×10-4 mol/L, respectively, which make it have potentially application value in Cr3+, Fe3+ and Al3+ detection in various water samples.

Key words: rhodamine, trivalent ions, fluorescence enhancement
