Abstract

A novel ratiometric fluorescent fluoride probe based on isoquinolinium salts has been designed and synthesized. According to the qualitative and quantitative studies the chemosensor has high selectivity and sensitivity to fluoride. Fluoride induces deprotection of the silyl protecting group of the hydroxyl group and causes a significant change in emission wavelength. The relative fluorescent intensity (I435/I540) increases linearly with F concentration in the range of 0–10.0 μmol/L. The dynamic determination process is monitored by 1H NMR spectroscopy.

新型基于异喹啉鎓盐的氟化物探针的设计,合成及应用

摘要

设计并合成了一种基于异喹啉鎓盐的新型配比荧光氟化物探针。根据定性和定量研究,化学传感器对氟化物具有很高的选择性和敏感性。氟化物引起羟基的甲硅烷基保护基的脱保护并引起发射波长的显着变化。相对荧光强度(I 435 / I 540)随着F 浓度在0–10.0μmol/ L范围内线性增加。动态测定过程通过1 H NMR光谱监测。
