Problems solved by technology

However, the reported Zn 2+ and Cd 2+ Fluorescent probes are mostly monoselective probes that can only detect Zn 2+ and Cd 2+ one of the metal ions
At the same time, due to Zn 2+ and Cd 2+ All are group IIB elements with highly similar physical and chemical properties, many Zn 2+ and Cd 2+ Single-selective fluorescent probes exhibited on Zn 2+ and Cd 2+ Similar fluorescent response signals, resulting in mutual interference in the detection of the two ions
Also, these Zn 2+ and Cd 2+ Fluorescent probes are mostly based on the analysis of single emission peak intensity, which is susceptible to interference on the fluorescence detection signal caused by various external factors such as instrument errors, changes in the detection environment, and human errors.

Description

technical field [0001] The invention relates to a derivative, a preparation method, an application, and a method for performing fluorescence analysis based on the derivative, in particular to an 8-aminoquinoline amide derivative, a preparation method, an application, and a method for fluorescence analysis thereof. Background technique [0002] Metals in organisms generally exist in the form of ions, and they play a very important role in various physiological and pathological processes of organisms. Zinc ions (Zn 2+ ) has a high content in nature and is the second most essential element for the human body. It is known as the "flower of life" for the human body. The right amount of Zn in the human body 2+ It can help wounds heal, promote the growth of babies, and maintain the normal functions of taste and smell. Lack of Zn 2+ It can lead to many diseases such as slow development and mental retardation, immune and reproductive function decline; Zn 2+ Excessive intake can ...
