一种含有2-吡啶基噻吩的噻唑小分子的合成及其对HSO3-的识别
Synthesis of Thiazole Small Molecule Containing 2-Pyridylthiophene and Its Recognition of HSO3-
摘要
Abstract
A new thiazole derivative(compound 1)was synthesized from 2-methyl-1-ethyl benzothiazole iodide,and then characterized by 1H NMR and MS.For the purpose of detection of HSO3-in aqueous solution,the interactions between the compound and some common anions,including Cl-,Br-,I-,NO3-,H2PO4-,CO32-,HCO3-,ClO4-,SO42-,Ac-,HS-and HSO3-were studied by UV-Vis spectroscopy.The results showed that HSO3-could be recognized by compound 1 with fast response time and low detection limit(0.21 μmol·L-1).Compound 1 also displayed recognition of HS- with a detection limit of 2.5 μmol·L-1,but the process took much longer time.Thus the presence of HS-presented no obvious interference for detecting HSO3-in a short time and low concentration.The new thiazole derivative can therefore be used for the rapid and selective detection of HSO3-.关键词
