C3 symmetrical fluorescent molecular probe as well as preparation method and application thereof

Abstract

The invention discloses a C3 symmetrical fluorescent molecular probe as well as a preparation method and application thereof and belongs to the technical field of metal ion analysis and detection. A structural formula of the C3 symmetrical fluorescent molecular probe is good in selectivity and high in sensitivity, is applied to a fluorescence sensor, can be used for specifically identifying copper ions and cadmium ions and is beneficial to analysis and detection of the copper ions and the cadmium ions in environment. The C3 symmetrical fluorescent molecular probe has the advantages that the preparation method is simple, the yield is high, the reproducibility is good, raw materials are easily obtained, and the cost is low, industrial production is facilitated and application prospect is good.

Description

Technical field [0001] The invention belongs to the field of metal ion analysis and detection technology, which involves one C 3 Symmetric fluorescent molecules and their preparation methods and detection applications for copper ions and cadmium ions. Background technique [0002] The fluorescent molecule probe means that the fluorescent molecules are introduced into the system through special design, and the molecular recognition information is converted into fluorescent signals to the outside world, which makes the conversation between people and molecules possible.Bridge of micro -world.In recent years, the fluorescent molecules probe has received great attention from the advantages of good selectivity, high sensitivity, low cost, easy operation, fast response time, and fast response time, and can be achieved. [0003] In the analysis of chemistry, many Sifine used to detect and identify certain metal ions.Setf base contains N and O atoms that are easy to form a key with metal...
