摘要：
A fluorescence probe of coumarin functionalized pillar [5]arenes(P5X) with aggregation induced emission (AIE) effect was synthesized. P5X showed strong AIE performance in DMSO/H2O (volume ratio:4:1) solution. When Fe3+ or Cu2+ were added to P5X solution, the blue fluorescence of the system was quenched. The lowest detection limits of P5X for Fe3+ and Cu2+ were 5.21x10(-6) mol/L and 2.48x10(-6) mol/L, respectively. In addition, the probe also had the advantage of strong anti-interference ability, and could realize efficient and sensitive detection of Fe3+ and Cu2+. The new method for the detection of Fe3+ and Cu2+ can provide a reference for the detection of related ions in environmental or biological fields.
