摘要
以常见荧光团罗丹明和萘酰亚胺设计并合成了一例用于比率型识别次氯酸根的荧光探针。结果表明,探针能够对次氯酸根实现高效专一的比率型选择,能够克服其他分析物的干扰。溶液体系荧光发射强度比率值(F_(590 nm)/F_(542 nm))在次氯酸钠浓度为0~1μmol/L范围内呈现良好的线性,其对次氯酸根的最低检出限为1.3×10^(-8) mol/L。探针可以定位于亚细胞器溶酶体中识别次氯酸根,并且能够应用于自来水等实际样品中检测次氯酸根。
A fluorescent probe for the ratiometric recognition of hypochlorite was designed and synthesized from rhodamine and naphthalimide.The probe could achieve high-efficiency and specific ratiometric selection for hypochlorite,and could overcome the interference of other analytes.The fluorescence emission intensity ratio(F590 nm/F542 nm)showed good linearity with the concentration of NaOCl in the range of 0~1μmol/L.The detection limit of hypochlorite was 1.3×10^(-8) mol/L.The probe could be located in the lysosomes to recognize hypochlorite,and could also be used to detect hypochlorite in real water samples.
