Embodiment Construction

[0021] The invention can complex various metal ions by using the structure of N-acetoxy o-methoxyaniline, so that it can be used to realize the analysis of trace ion content. In the long-term research and development process, the applicant has extensively detected the metal ions that can be complexed by the compound structure of the present invention, and found that it is effective for Ca 2+ 、Cd 2+ 、 Co 2+ 、Cr 3+ 、Cu 2+ , Fe 2+ , Fe 3+ , Hg 2+ 、K + , Mg 2+ , Mn 2+ 、Na + 、Ni 2+ , Pb 2+ , Zn 2+ And lanthanide metal ions have certain binding ability, among them, especially has good complexing ability for zinc ions, has significant and specific binding complexing ability for zinc ions, can be used as zinc ion effective carrier. By introducing a fluorescent group at the para-position of the above-mentioned aniline structure, based on the principle of photoinduced electron transfer, when the ion content changes, its fluorescence intensity changes accordingly, so the io...

Abstract

The invention discloses a fluorescent probe for detecting the metal ion content in water, wherein a rhodamine fluorophore is introduced into the molecule of N-o-anisidine acetate used as a metal ion complex to generate the fluorescent indicator for metal ions, particularly zinc ions. According to the present invention, the compound can further be used for in situ imaging of cells, can be used forthe continuous detection of metal ion concentrations in various environments, and especially can be used for the continuous determination of the zinc ion concentration in water.

Description

technical field [0001] The invention belongs to the field of organic compounds, and in particular relates to an organic compound which can be used for detecting the content of metal ions in water and related applications. Background technique [0002] Water is the source of life and the material basis for the survival of human beings and all living things. With the rapid development of our country's economy, people rely too much on the input of water resources, resulting in a large amount of waste of water resources, water pollution and domestic water shortage. Especially with social progress and diversification of industrial development, complex pollutants lead to aggravated water pollution. Facing the serious shortage and pollution of water resources, we must establish and practice the concept that green water and lush mountains are invaluable assets, adhere to green and harmonious development, and insist on sustainable use of water resources, which puts forward higher re...
