Abstract

The invention discloses a dikaryotic cobalt complex and a preparation method thereof. The dikaryotic cobalt complex consists of a dikaryotic cobalt complex crystal, wherein the chemical formula of the dikaryotic cobalt complex crystal is Co2(H2O)4(C12H9N3)4(C8H4O4)2.2H2O. The dikaryotic cobalt complex crystal belongs to a triclinic crystal system, and the space group is P-1. The dikaryotic cobalt complex is prepared by adopting a hydrothermal synthesis method by the following steps: mixing cobalt chloride hexahydrate, 2-(3-pyridyl)benzimidazole, 1,3-phthalic acid and water by stirring; placing the mixture into an enclosed container and reacting for at least one hour at the reaction temperature of at least 150 DEG C; performing solid-liquid separation. The dikaryotic cobalt complex crystal emits strong fluorescent light at the central wavelength of 450 nanometers under the excitation of ultraviolet light of which the wavelength is 380 nanometers, indicating that the dikaryotic cobalt complex crystal has high fluorescence characteristic.

Description

technical field [0001] The invention belongs to the field of metal-organic complex crystal materials, in particular to a dinuclear cobalt complex and a preparation method thereof. Background technique [0002] There are many kinds of nitrogen heterocyclic ligands, such as pyridine, benzimidazole, triazole, etc., which are easy to coordinate with metals. In many metal-organic coordination polymers, benzimidazole always plays an important role. At present, the coordination polymers with benzimidazole as the building block are mainly developed in four aspects: (1) alkyldiimidazole derivatives as bridging ligands; (2) aromatic hydrocarbon imidazole derivatives as bridging ligands. (3) Imidazole deprotons to form a bridging ligand to form a coordination polymer; (4) Purposefully utilizes the uncoordinated N-H groups on imidazole to form a hydrogen bond network. [0003] At present, the research on benzimidazole supramolecular complexes mainly focuses on the use of alkyl and aryl...
