Abstract

The invention provides a preparation method and application for a fluorescent probe capable of rapidly detecting an aluminum ion in a pure water solution. The preparation method comprises the following steps: dissolving 2-aminophenol in anhydrous methanol so as to obtain a 2-aminophenol methanol solution; dissolving 5-bromosalicylaldehyde in anhydrous methanol so as to obtain a 5-bromosalicylaldehyde methanol solution; adding the 2-aminophenol methanol solution into the 5-bromosalicylaldehyde methanol solution, carrying out stirring at room temperature, then carrying out filtering, retaining a filter cake, and carrying out flushing with anhydrous methanol so as to obtain the fluorescent probe 2-aminophenol-5-bromosalicylaldehyde. The invention has the following advantages: the synthetic method of the fluorescent probe is simple, is easy to operate and has low cost; and the synthesized fluorescent probe has simple structure, can show significant fluorescence enhancement phenomenon in the presence of Al3+ in an aqueous solution, has good selectivity to Al3+, and can detect the aluminum ion in the aqueous solution.

Description

technical field [0001] The invention relates to a preparation method and application of a fluorescent probe for rapidly detecting aluminum ions in pure aqueous solution. Background technique [0002] Aluminum ions are widely used in food additives, water treatment, medicines and tableware. However, when there is too much aluminum in the human body that exceeds the limit of body absorption, it will cause many health problems such as Alzheimer's disease and Parkinson's disease Syndrome. [0003] Conventional optical materials can cause fluorescence quenching when they are aggregated or solid. In 2001, the phenomenon of aggregated fluorescence was first proposed by Tang Benzhong's experimental group. The aggregated fluorescent molecules have no obvious fluorescence emission in the dissolved state, but emit strong fluorescence in the aggregated state. Therefore, this aggregated fluorescent molecule has a good application prospect in fluorescent dyes, light-emitting diodes, and...
