Embodiment 1

[0030] At room temperature, weigh 0.198g (2mmol) of cuprous chloride, 1.307g (2mmol) of benzimidazole phosphine ligands and 0.524g (3mmol) of triphenylphosphine into a mixed solution of 20ml of dichloromethane and acetonitrile (volume ratio of dichloromethane to acetonitrile = 4:1), heated to 45° C. and kept stirring at this temperature for 2 hours. The reacted solution was filtered and transferred to a 30ml small glass bottle, and naturally volatilized for 72 hours to obtain crystals of the complex, which were filtered out, washed with a small amount of acetonitrile, and vacuum-dried to obtain the final product with a yield of 75%.

Embodiment 2

[0032] At room temperature, weigh 0.297g (3mmol) of cuprous chloride, 2.045g (3mmol) of benzimidazole phosphine ligands and 0.786g (3mmol) of triphenylphosphine into a mixed solution of 25ml of dichloromethane and acetonitrile medium (volume ratio of dichloromethane to acetonitrile=4:1), heated to 45° C. and kept stirring at this temperature for 3 hours. The reacted solution was filtered and transferred to a 30ml small glass bottle, and naturally volatilized for 96 hours to obtain complex crystals, which were filtered out, washed with a small amount of acetonitrile, and vacuum-dried to obtain the final product with a yield of 76%.

Abstract

The invention discloses a mononuclear copper complex with fluorescence property and a preparation method thereof. The molecular formula of the complex is C63H51CuClN3O2P2, and the structural formula of the complex is shown in the specification. The crystal of the complex belongs to a triclinic system, and the cell parameters are as follows: alpha = 79.21 degrees, beta = 87.78 degrees and gamma = 86.12 degrees. Each complex molecule comprises a copper ion, a benzoimidazolylphosphine ligand and a triphenylphosphine auxiliary ligand. In the crystal, Cu ions in the center of the complex are respectively coordinated with Cl ions, N and P atoms in benzimidazolylphosphine ligands and P atoms in the auxiliary ligand triphenylphosphine to form a tetra-coordinated twisted tetrahedral configuration.The invention also provides a preparation method of the complex. The method is mild in reaction condition, simple in preparation process and low in cost. The copper complex has good thermal stabilitywhile having fluorescence property.

Description

technical field [0001] The invention belongs to the technical field of metal-organic complex synthesis, and in particular relates to a mononuclear copper complex with fluorescence performance and a preparation method thereof. Background technique [0002] As one of the important research topics in materials chemistry today, metal-organic complexes not only have structural aesthetic value, but also have good application prospects in the fields of luminescence, magnetism, adsorption, hydrogen storage, catalysis, and separation. In particular, the construction of coordination polymers with highly thermally stable structures and special physicochemical properties through the coordination of metal ions and organic multifunctional ligands has attracted great interest. However, designing and constructing such materials with special structures and functions is an innovative technology, which is very challenging, especially materials with good thermal stability and optical properties...
