Embodiment Construction

[0010] We chose cuprous iodide and 2-mercaptobenzothiazole as the reaction raw materials, ethanol, acetonitrile and hydroiodic acid as the reaction raw materials or solvents, and obtained the compound Cu under solvothermal conditions. 4 I 4 (Etmbt) 4 single crystal. The organic component Etmbt is produced by the in-situ ethylation of the raw material 2-mercaptobenzothiazole under acidic conditions.

[0011] The beneficial effect of the present invention is that the synthetic raw material of the involved tetra-nuclear copper-iodine cluster material is non-toxic, easy to obtain, simple in synthesis thinking, easy to operate and low in cost. The tetranuclear copper-iodine cluster material involved in this invention has excellent photoluminescence properties, and can detect o-nitrophenol with high selectivity in water systems, and is not affected by its isomers m-nitrophenol and p-nitrophenol. , and the interference of other common organic substances, with high sensitivity and ...

Abstract

The invention provides synthesis of a copper-iodine four-core molecular cluster Cu4I4 (Etmbt)4 and nitrophenol selective fluorescent selective sensing application of the chair type copper-iodine cluster. The invention aims at synthesizing a copper-iodine-based sensing material Cu4I4 (Etmbt)4 capable of selectively sensing and identifying nitrophenol, wherein Etmbt is 2-ethylmercaptobenzothiazole.The material contains one ladder-shaped Cu4I4 core and four Etmbt ligands and can emit relatively strong yellow green phosphorescence. The copper-iodine four-core molecular cluster Cu4I4 (Etmbt) can be obtained by taking cuprous iodide, the 2-ethylmercaptobenzothiazole, ethanol, acetonitrile and hydroiodic acid to react under a solvent thermal condition and can be used for selectively sensing andidentifying o-nitrophenol in wastewater.

Description

technical field [0001] The present invention relates to a phenolic compound sensing application of a copper-iodine-based cluster material, in particular to a chair-type copper-iodine tetranuclear molecular cluster Cu 4 I 4 (Etmbt) 4 The synthesis and its o-nitrophenol sensing application, where Etmbt = 2-ethylmercaptobenzothiazole. Background technique [0002] As important organic chemical raw materials, phenolic substances can be used as solvents, reagents and disinfectants. They are used in synthetic fibers, synthetic rubber and other fields, and are common toxic and harmful substances in production and life. With the rapid development of the domestic chemical industry, the phenol-containing wastewater discharged from the phenolic substance production industry and downstream industries that use phenolic substances as raw materials, such as pharmaceutical production plants, steel mills, and synthetic fibers, has increased year by year. Therefore, while meeting people's ...
