A kind of pentacene fluorescence ratio probe and its preparation method and application

Abstract

A pentacene fluorescence ratio probe and its preparation method and application. The structural formula of the pentacene fluorescence ratio probe is shown in FIG. 3 . The novel pentacene fluorescent ratio probe designed and synthesized by the present invention fully utilizes the D-π-A structure and the characteristics of the fluorescent ratio probe, thereby avoiding the detection process due to its own main body and detection solvent. The result is interference. With this design, the probe showed excellent selectivity for methanol, demonstrating the initial application value of this probe in the food field.

Description

A kind of pentacene fluorescence ratio probe and its preparation method and application 【Technical field】 The present invention relates to molecular fluorescent probe technical field, particularly a kind of pentacene fluorescent ratio probe and preparation method thereof law and application. 【Background technique】 In recent years, fluorescence analysis technology has gradually become an important method in modern analysis technology, because of its high sensitivity. and selective specificity for identification, detection and monitoring of some important substances in biology, environment, food and medicine has become the main application direction. Although some conventional detection methods such as high-resolution liquid chromatography, mass spectrometry, atomic absorption spectroscopy, Methods such as inductively coupled plasma atomic emission spectrometry and electrochemical sensing have been used for the analysis of related substances. These detection methods...
