Preparation,inentification and application of pyrenebutyric acid-silica and diphenylanthracene-silica reagent on fiber-optic chemical sensor

摘要

@@ 1 IntroductionrnTwo new fiber-optic chemical sensor based on multiple fluorescence quenching is described. The reagent phases of the sensors are stable in organic solvent. The first reagent phase was constructed by covalent bonding pyrenebutyric acid (PBA) to the surface of glass (PBA-SiO2). It was identified by IR spectrum, fluorescence spectra and TGA analysis. And it can determine Rutin in ethanol.
