Embodiment 1

[0071] 1. The synthetic route of the probe:

[0072]

[0073] The specific preparation method of the probe: in a 100ml three-necked flask, add tris(2-aminoethyl)amine (4.0g, 27.36mmol), rhodamine B (1.638g, 3.42mmol), 60ml of absolute ethanol, nitrogen Under protection, reflux for 36h, evaporate ethanol under reduced pressure, and use CH 2 Cl 2 (3×100ml) extraction, the organic phase was dried overnight with anhydrous magnesium sulfate, and the solvent was evaporated to obtain a red viscous substance, which was separated by silica gel plate chromatography, and the eluent was methanol / three Chloromethane / triethylamine to obtain 1.71 g of a colorless viscous intermediate with a yield of 87.3%. The structural characterization data are as follows: 1 H NMR (500MHz, CDCl 3 )δppm 7.89 (d, J=5.0Hz, 1H, ArH), 7.44-7.46 (br, 2H, ArH), 7.10 (bs, 1H, ArH), 6.40~6.42 (m, 4H, ArH), 6.27 (d ,J=5.0Hz,2H,ArH),3.34(q,J=10.0Hz,8H,NCH 2 CH 3 ),3.15(m,2H,NCH 2 CH 2 N),2.55-2.57(m,4H,NC...

Abstract

The invention discloses a method of using a probe to simultaneously detect trace Al<3+> and/or I<->. The chemical name of the probe is tri[bis(naphthylthioureido)-rhodamineformamido]ethylamine. Fluorescent spectrometry and UV-visible absorption spectrum are used to detect Al<3+> and I<->, or visual colorimetry is used to detect Al<3+> ions. The probe can simultaneously detect specific metal ions (aluminum ions, eg.) and negative ions (iodine ions, eg.), can also detect aluminum ions through visual detection, and is beneficial for the analysis on a complicated microscopic system.

Description

technical field [0001] The invention relates to a probe and a method for detecting trace ions using the probe, in particular to a probe and using the probe to simultaneously detect trace Al 3+ and / or I - Methods. Background technique [0002] As an important analysis and detection technology, fluorescent probes are widely used in the fields of chemistry, biology and environmental science due to their simplicity, high sensitivity, real-time and visual detection. Many important metal ions and anion fluorescent probes related to life and environment have been reported. [0003] Aluminum is the most abundant element in the earth's crust after oxygen and silicon, and is widely used in daily life, such as food additives, kitchen utensils, paper and packaging materials, pigments, pharmaceutical products, and water treatment. Aluminum is not an essential element for the human body, and excessive intake can lead to diseases such as osteoporosis, anemia, Parkinson's disease and Alz...
