Abstract

The invention discloses a platinum-based coordination fluorescent bicyclic complex, a preparation method thereof and an application of the platinum-based coordination fluorescent bicyclic complex in explosive detection. A perylene diimide group with high fluorescence stability is designed into a tetradentate pyridyl ligand, the tetradentate pyridyl ligand is introduced into construction of a supramolecular metal annular complex through an effective metal organic coordination effect, and the tetradentate pyridyl ligand, a metal platinum (II) ligand and six bidentate sodium carboxylate ligands are spontaneously assembled through a one-pot method to obtain six supramolecular metal bicyclic complexes. According to the preparation method, supramolecular fluorescent metal bicyclic rings are constructed by introducing fluorescent molecules perylene diimide, and finally simple molecules are spontaneously assembled through metal organic coordination, so that interference of cationic compounds in the environment on explosive detection can be effectively resisted, and the problems of complex synthesis route and long time consumption are solved.

Description

technical field [0001] The invention belongs to the technical field of supramolecular chemistry, and in particular relates to a platinum-based coordinated fluorescent bicyclic complex, a preparation method thereof, and an application in explosive detection. Background technique [0002] Since modern times, with the rapid development of the chemical and chemical industry, global environmental protection issues have become prominent, and people are constantly facing new challenges. As an important high-energy compound, nitroaromatic compounds have been widely synthesized and used. If such compounds are leaked during production and transportation, there is not only a risk of explosion, but also damage to the environment and a threat to human health. Therefore, it has become one of the research hotspots in the current scientific community to continuously develop fast and effective detection methods for p-nitroaromatic explosive compounds. [0003] Among various materials used ...
