Problems solved by technology

[0005] However, due to the complexity of the structure of organic ligands and the diversity of coordination modes of organic ligands and metals, the synthesis of metal-organic coordination polymers, the separation and purification of products, and the determination of structures are not easy.
Especially for metal-organic coordination polymers with good electroluminescent properties, the synthesis and structure determination of coordination polymers with new structures are relatively difficult.

Description

technical field [0001] The invention relates to the field of photoelectric materials, in particular to a Ni(II) coordination polymer and its preparation method and application. Background technique [0002] Organic electroluminescence is a phenomenon in which electrical energy excites organic materials to emit light. As early as 1963, M. Pope et al. of New York University in the United States discovered the electroluminescence phenomenon of organic compound single crystal anthracene. In 1987, C.W.Tang used organic electroluminescent raw materials, 8-hydroxyquinoline aluminum as the light-emitting layer, and vacuum-evaporated to make a low-driving voltage, high-efficiency, high-brightness multilayer organic light-emitting device (ie OLED device) . [0003] Compared with traditional LCD display devices, OLED display devices have the advantages of thinness, lightness, wide viewing angle, active light emission, low cost, fast response speed, low energy consumption, low driving...
