Problems solved by technology

At present, there have been many reports on the research of life and environment-related ions by fluorescent probe method, but most of them are single-probe single-target detection, that is, one probe can only detect one kind of ion, and single-probe multi-target detection cannot be realized.
[0004] Therefore, due to the presence of probes, single-probe multi-target detection cannot be realized, and the detection cost is high and the detection efficiency is low.
And it is not conducive to the analysis of complex microscopic systems

[0081] Its synthetic route is as follows:

[0082]

[0083] The specific preparation method is:

[0084] (1)N 2 In a dry 500ml three-neck flask under protection, add 40mmol of p-xylylene dimethyl ether, 200mmol of tetrabutylethylenediamine and 140ml of ether to obtain product A;

[0085] (2) Product A is cooled to below 0°C to obtain Product B;

[0086] (3) Add 100ml of n-butyllithium with a concentration of 1.6M to product B, continue to react at 0°C for 10 minutes after the addition, reflux the reaction solution for 20 hours, and obtain product C after the reaction solution is cooled to room temperature;

[0087] (4) Add 220 mmol of N,N-dimethylformamide to product C, and stir overnight at room temperature; obtain product D;

[0088] (5) Add 100ml of water to pr...

Abstract

The invention discloses a probe for detecting a variety of ions and application thereof. The probe takes tris (2-aminoethyl)amine, O-aminothiophenol and hydroquinone dimethyl as raw materials and is obtained by reaction. The probe disclosed by the invention can realize the single-probe multi-target detection and is low in detection cost and high in detection efficiency. The analysis on a complex microscopic system is facilitated.

Description

technical field [0001] The invention relates to a probe for detecting ions and its application, in particular to a probe capable of detecting multiple ions and its application. Background technique [0002] Fluorescent probes can detect specific ions with high sensitivity and high selectivity, and have the characteristics of low detection cost, fast speed, simple equipment, simple and intuitive methods, etc., and are widely used in the field of analysis and detection. The probe can not only accurately measure the content of specific ions by spectrum, but also perform rapid qualitative and semi-quantitative detection through visual colorimetry; it can not only use fluorescence / absorption enhancement, but also use the ratio fluorescence / absorption detection method to improve the sensitivity of the analysis. accuracy and selectivity. Using the ratio absorption detection method is different from the detection of the change of absorbance at a single wavelength, which can overcom...
