Highly effective two-color white light high polymer material and method for making same

Abstract

The invention relates to a highly effective two-tone white light high molecular material and it's preparing method in the field of lighting material technology. The chemical structure of the highly effective two-tone white light high molecular material is as the right type, wherein x=0.00001-0.5. The preparing method is that it uses polymer fluorenes as blue light structure unit, 4, 7-2 (4-(N-phenyl -N-(4-methyl phenyl) amino) phenyl)-2, 1, 3 -benzodithiazole as orange light structure unit, it uses combined polymerization mode to lead the orange light work unit into the blue light macromole fundamental chain by chemical key mode to prepare for the highly effective two-tone white light high molecular material.

Description

technical field

[0001] The invention belongs to a high-efficiency two-color white light polymer material and a preparation method thereof. technical background

[0002] Since Burroughs et al. of the University of Cambridge reported the electroluminescence phenomenon of poly-p-phenylene vinylene (PPV) for the first time in 1990, polymer electroluminescent materials and devices (PLEDs) have the advantages of simple process, low cost, and easy realization of large-screen Outstanding features such as displays and flexible displays have received a lot of attention and investment. So far, red, green, and blue polymer luminescent materials have met the requirements for practical use; in contrast, the performance indicators of white polymer luminescent materials, including efficiency, life, color coordinates, etc., are still far from practical use. There is a big gap, but white polymer luminescent materials and devices have very broad application prospects in background light sourc...
