Problems solved by technology

[0003] Generally speaking, the fluorescence detection method requires the detected substance to have fluorescence characteristics, or have active sites that can interact with fluorescent substances, while dichloromethane molecules themselves cannot emit fluorescence, and the molecules themselves lack active interaction sites, which is different from general It is difficult for fluorescent detection materials to interact, so there is no relevant research report on the detection of dichloromethane by fluorescence technology

Abstract

The invention discloses a Ag(I) coordination compound with the dichloromethane fluorescence enhancement effect, and relates to the field of fluorescence detection materials. The chemical formula of the Ag(I) coordination compound is [Ag2(DAT)2(NO3)2]n, wherein Ag and Cl in dichloromethane have the extra-high compatibility, a dichloromethane molecule can be actively adsorbed to the Ag(I) coordination compound, an original energy elimination channel is interdicted, and therefore the Ag(I) coordination compound has the dichloromethane fluorescence enhancement effect. According to the Ag(I) coordination compound, silver nitrate serves as metal salt, 5,12-di-aza-tetracene serves as an organic ligand, and the Ag(I) coordination compound is prepared with the natural volatilization method of three solvent components of the dichloromethane / methyl alcohol / acetonitrile; the method is simple, the reaction condition is wild, and large-batch production is easy. The invention also provides application of the Ag(I) coordination compound. The Ag(I) coordination compound serves as a fluorescence detection material, and is used for rapid and sensitive fluorescence detection of dichloromethane molecules free of fluorescence.

Description

technical field [0001] The invention relates to the field of fluorescence detection materials, and in particular to an Ag(I) complex having a dichloromethane fluorescence enhancement effect, a preparation method and an application. Background technique [0002] As an important chemical raw material and solvent, dichloromethane has important applications in many fields such as pharmaceuticals. Therefore, it is of great significance to develop a new technology that can quickly and accurately detect the residual amount of dichloromethane in corresponding products. Among the various new detection technologies that are popular at present, gas chromatography is the most widely used, and it has many defects and deficiencies. The main reason is that the operation process is complicated and cumbersome, which is not conducive to the rapid and convenient detection of products. The advantages are widely used. Fluorescence detection methods can be mainly divided into quenching type and ...
