VOC fluorescent sensing material based on cuprous complexes

The invention discloses a VOC fluorescent sensing material based on cuprous complexes, a preparation method of the VOC fluorescent sensing material and VOC fluorescent sensing application. A luminouscomplex is prepared by complexing univalent copper salts and ligands; the molecular structure is Cu(Xantphos)I; in the formula, the Xantphos is an electrically neutral diphosphine ligand of 4,5-bis(diphenylphospheno)-9,9-dimethylxanthene; I is a halogen iodide ligand. The complex has the advantages of easy purification of small molecules, and also has high thermal stability. The material is obtained by direct mixing and reaction on the CuI and the ligand acetonitrile solution and dichloromethane solution. The complex has the advantages that the process is simple and convenient; the equipment is simple; the raw materials can be easily obtained; the cost is low, and the like. The material can be used as the VOC fluorescent sensing material, and has the good selective fluorescent response tomethylamine steam.

A highly efficient palladium/copper cocatalytic system for direct arylation of heteroarenes: An unexpected effect of Cu(xantphos)I

"Chemical equation presented" Heteroarenes are important structural moieties in many chemical industry fields. A highly efficient Pd/Cu-catalyzed C-H arylation method for a range of heterocycles has been discovered. It was found that the key to the success of this transformation is a combination of a palladium catalyst and a well-defined copper cocatalyst. The efficiency and low loadings of catalyst (0.25 mol %) and cocatalyst (1 mol %) together with the mild reaction conditions demonstrate this method to be practically useful and mechanistically interesting.
