Abstract

The invention discloses a transition metal compound with green fluorescence emission characteristic and a preparation method. A chemical formula of the transition metal compound is M2(HL)3(NO3), the M in the formula is divalent transition metal, and the HL is 1,1-[7,7'-bis-(8-hydroxyl anion quinoline)]. The invention further discloses the preparation method of the transition metal compound with the green fluorescence emission characteristic. The two-nuclear transition metal cluster structure compound with the green fluorescence emission characteristic provided by the invention has the advantages of simple preparation method, greenness, environmental friendliness and good potential application prospect in a fluorescence material aspect.

Description

technical field [0001] The invention relates to a transition metal complex with green fluorescence emission characteristics and a preparation method. Background technique [0002] Since Tang and Van Slyke of U.S. Kodak Company reported Alqs (q=8-hydroxyquinoline) as the double-layer green organic electroluminescent (EL) device of light-emitting layer in 1987, 8-hydroxyquinoline and its derivatives have been used as complex Metal-organic complex luminescent materials have attracted extensive attention. 8-Hydroxyquinoline is a monovalent bidentate chelating ligand, which can form metal-organic complex fluorescent materials with different coordination modes with various metals. People continue to find metal-organic complex fluorescent materials with better performance by changing the structure of metal ions and ligands. Because the preparation process is simple and easy to control, in the development of derivatives of 8-hydroxyquinoline, the research is to obtain 1,1-[7,7'-di...
