Abstract

The invention relates to a cuprous cyanide complex of a 2-aminopyrimidine ligand and a preparation method of the cuprous cyanide complex. The cuprous cyanide complex has a chemical formula [Cu2(CN)2(PymNH2)]n, wherein PymNH2 is 2-aminopyrimidine. The cuprous cyanide complex is a novel three-dimensional framework cuprous complex containing the 2-aminopyrimidine ligand and is simple in synthetic method, easy to crystallize, high in synthetic yield and easily available in raw materials; a crystal material of the complex is high in thermal stability and good in green luminescent properties, and can serve as a green luminescent material to be further applied in the field of material chemistry.

Description

technical field [0001] The invention belongs to the technical field of functional complexes and molecular-based optical materials thereof, and particularly relates to a 2-aminopyrimidine ligand cuprous cyanide complex and a preparation method thereof. Background technique [0002] Functional complex optical materials generally have the characteristics of good thermal stability, high fluorescence efficiency and easy film formation, and are considered to be one of the research hotspots in the field of functional complexes and the most promising category in recent years. Luminescent material. Therefore, the research on the photophysical and photochemical properties of functional complexes has aroused great interest of scientists. At present, the central metal atoms of these photofunctional complexes are mainly transition metals in the fifth and sixth periods, especially the transition metals of the eighth subgroup, osmium, iridium, and platinum. Disadvantages such as high cos...
