Abstract

The invention discloses application of a water-soluble fluorescent conjugated polymer to the detection of a nitroaromatic hydrocarbon. The structural formula of the polymer is as shown by a formula 1 which is as defined in the description. The specific water-soluble fluorescent conjugated polymer which is provided by the invention has favorable application to the detection of the nitroaromatic hydrocarbon by serving as a sensor. The water-soluble fluorescent conjugated polymer contains a water-soluble group; the water-soluble fluorescent conjugated polymer comprises two parts, wherein one part is a carbazole conjugated backbone existing in a form of a pi-pi conjugated system, so as to guarantee the optical property of the polymer; the other part contains a polyhydric water-soluble group, so as to meet the solubility, in a water phase, of the polymer. A polymer chain can be completely and uniformly dispersed in a water-phase environment; the direct contact between an analyte and the polymer is facilitated; the signal magnification effect of the polymer is realized.

Description

technical field

[0001] The invention specifically relates to the application of a water-soluble fluorescent conjugated polymer in the detection of nitroaromatics. Background technique

[0002] As a new class of polymer materials, water-soluble conjugated polymers have attracted much attention in recent years. Due to the characteristic of being able to disperse uniformly in the water phase, water-soluble conjugated polymers are widely used in various fields. However, there are few reports on the use of water-soluble conjugated polymers for the detection of nitroaromatics in water.

[0003] Nitroaromatic compounds (trinitrotoluene TNT, dinitrotoluene DNT) are important components of explosives, and nitroaromatics are also harmful to human health. Therefore, it is of great significance to explore the on-site detection technology of micro-trace nitroaromatics for people's life and property safety and environmental protection. In reality, there are many studies on nitroaromati...
