摘要

通过将5-氨基间苯二甲酸乙酯与葡萄糖相连

设计合成了一种具有良好水溶性的荧光探针PN

该探针能够高选择性地识别水中的汞离子

与汞离子作用后会引起荧光猝灭和紫外吸收减弱。将探针PN固载于介孔硅材料SBA-15

得到材料化的荧光探针SBA-PN

SBA-PN可在pH值4~10范围内使用

对水中的汞离子具有更好的选择性和识别能力。固载之后的探针在实际应用中更加方便

适用于水体系中汞离子的识别。

Abstract

Fluorescent molecular probes with high sensitivity

high selectivity

fast and convenient real-time in-field testing

are widely used to detect heavy metal ions. In this paper

we designed and synthesize a water-soluble fluorescent probe PN. PN could selectively detect mercury(Ⅱ) ions in aqueous solution. The small molecule probe PN afforded fluorescent intensity quench and decrease absorption of UV/Via spectrum in the presence of mercury(Ⅱ) ions. In order to achieve practical applications

PN is immobilized on the surface of SBA-15. The immobilization of fluorescent probe (SBA-PN) could selectively and sensitively detect mercury(Ⅱ) ions in a relatively wide pH range(4-10). Comparing with PN

the composite probe is more suitable for the recognition of mercury(Ⅱ) ions in water.
