Abstract

The invention discloses a fluorescent compound and a fluorescent probe based on the fluorescent compound as well as a preparation method and an application of visible test paper, and belongs to the technical field of the preparation of the fluorescent compound. Cholesterol (cholic acid) and 8-hydroxyquinoline are respectively used as a side-chain structure and an end-capping structure to be simultaneously introduced into para-position di-benzyne substituted benzene so that a novel fluorescent compound is synthesized and has all supermolecule characteristics. The fluorescent probe prepared by utilizing the fluorescent compound is good in photochemical stability in a water phase and capable of high sensitively and selectively identifying sarin nerve gas and simulants thereof. The preparation method of the fluorescent compound is simple to operate and moderate in reaction condition; the prepared fluorescent probe is good in photochemical stability, high in sensitivity and good in selectivity; when the fluorescent molecular probe is combined with a commodity fluorescent instrument, the environmental sarin poison gas and simulants thereof can be sensitively detected.

Description

technical field

[0001] The invention belongs to the technical field of preparation of fluorescent compounds and fluorescent probes thereof, and specifically relates to a preparation method and application of a fluorescent compound, a fluorescent probe based on the fluorescent compound, and a visualization test paper. Background technique

[0002] Chemical warfare agents (CWAs) refer to various chemical substances that are used for war purposes and can poison or kill enemy humans, animals and plants on a large scale. Because of its easy production, strong toxicity, high lethality, wide range of damage, and long-lasting poisonous effect, it was used as a weapon of mass destruction in the two world wars and some local wars, not only causing a large number of deaths of people and animals , leading to the formation of large-scale poisoning areas and poison cloud transmission belts, and will affect the utilization of soil, water sources and other facilities for a long time afterwa...
