Description

technical field [0001] The invention relates to a complex, in particular to a complex of trinuclear copper, imidazole-4,5-dicarboxylic acid and o-phenanthroline, a preparation method thereof, and an application in the field of luminescent materials. Background technique [0002] In the field of luminescence, the research of organic materials has been paid more and more attention by people. Because there are many kinds of organic compounds, good adjustability, rich colors, high color purity, and relatively flexible molecular design. According to different molecular structures, organic light-emitting materials can be divided into: (1) organic small molecule light-emitting materials; (2) organic polymer light-emitting materials; (3) organic complex light-emitting materials. These luminescent materials have their own characteristics in terms of luminescent mechanism, physical and chemical properties, and applications. However, the low luminous intensity and poor stability of o...
