以罗丹明B为原料,通过"点击化学"合成和表征了一种苯并噻唑-罗丹明类双通道比色和荧光增强型探针(L),并研究了其光谱性质.实验结果表明,在甲醇溶液中L对三价金属离子Fe3+、Cr3+和Al3+具有较高的选择性和灵敏度,不受其它二价金属离子及一价金属离子影响,抗干扰能力强.探针L对Fe3+、Cr3+和Al3+的检测限分别为9.7×10-5、6.9×10-5、1.4×10-4mol/L,表明对Fe3+、Cr3+和Al3+检测具有潜在的应用价值.

A novel rhodamine-based probe L was synthesized from rhodamine B through "click chemistry". It showed that probe L acted as a naked-eye and "turn on" fluorescent probe for Fe3+, Al3+ and Cr3+ recognition.L is highly selective to trivalent ions (Fe3+, Al3+ and Cr3+) over other monovalent or divalent ions in CH3OH. Detection limits of probe L for Fe3+, Cr3+and Al3+ are 9.7×10-5, 6.9×10-5 and 1.4×10-4 mol/L, respectively, which could make it potentially applicable in Fe3+, Cr3+ and Al3+ detection.

Key words: rhodamine, benzothiazole, click chemistry
