摘要
报道了一种基于能量转移的荧光检测硝基芳香族化合物(NACs)的方法.以1,8-萘酰亚胺功能化的柱[5]芳烃为原料,通过超分子自组装制备了荧光超分子聚合物(P5NPs).当加入NACs时,P5NPs溶液的固有荧光强度会迅速降低甚至淬灭,这可以归因于P5NPs向—NO2基团的能量转移.研究表明,P5NPs对NACs具有普遍的灵敏响应.因此,本研究通过超分子方法构建了荧光聚合物P5NPs,能够高灵敏检测NACs,为开发新一代多功能荧光超分子聚合物开辟了广阔的前景.
Abstract
The design of smart strategies for monitoring environmental pollution and disease biomarkers has attracted tremendous research attention.Herein,we report a fluorescence method based on energy transfer to detect nitroaromatic compounds(NACs).The fluorescent supramolecular polymers(P5NPs)are built from 1,8-naphthalimide-functionalized pillar[5]arenes(P5Ns)through supramolecular self-as-sembly.Upon the addition of NACs,the intrinsic fluorescence intensity of the P5NPs solution decreases or even quenches quickly,which can be ascribed to the energy transfer from P5NPs to—NO2 groups.In addition,the P5NPs show exceptional sensitivity and universality toward detecting various NACs.This work will open new perspectives to develop new multifunctional fluorescent supramolecular polymers for sensing and detection applications.
