Description
Technical Field
The invention belongs to the technical field of fine organic synthesis, and particularly relates to a dehydroabietylamine silver ion fluorescent probe and a preparation method thereof.
Background
Silver is one of noble metals having good thermal and electrical conductivity and a few natural antibacterial substances. Due to their special properties, silver ions and silver nanoparticles have recently attracted attention in many fields such as medical devices, biomedicine, and textiles.
However, the excessive silver is harmful to the environment and human body, and the aquatic organisms such as fish and the like are killed or concentrated in the aquatic organisms due to the excessive silver contained in the water. Repeated exposure of silver to the human body can lead to the functional changes of heart enlargement, growth retardation, liver and the like, so that the detection of the silver content is particularly important. At present, the conventional methods such as voltammetry and electrothermal atomic absorption spectrometry are commonly used. These methods are very good for quantitative or qualitative detection, but have many drawbacks, such as too long detection time, too high sample requirement and cumbersome processing, which make real-time monitoring of silver ions impossible.
Thus, highly selective and highly sensitive Ag can be developed + The detection method has important significance for environmental protection and human health. In recent years, many organic fluorescent probes are researched for detecting metal ions, such as rhodamine fluorescent probes for detecting silver ions and coumarin fluorescent probes for detecting silver ions, but no reports related to the synthesis of dehydroabietic acid-based fluorescent probes for detecting silver ions exist.
