Document Type and Number:
WIPO Patent Application WO/2022/262159
Kind Code:
A1
Abstract:
The present invention relates to the technical field of n-type semiconductor materials. Disclosed are an n-type conjugated polymer, a preparation method therefor, and an application thereof. In the method, by taking a solvent as a reaction medium, a reaction monomer is reacted under the action of a substance having oxidability to obtain an n-type conjugated polymer. The n-type conjugated polymer comprises one or more polymerization units, and the polymerization units are of a structure of formula (I) and/or a structure of formula (II), and/or in an enol-type transformation form corresponding thereto. According to the present invention, an aromatic diketone substance having active methylene is a raw material, and is subjected to a direct polymerization reaction by means of the substance having the oxidability. The reaction does not require a noble metal for catalysis, and the n-type conjugated polymer is not sensitive to the reaction atmosphere, has a simple process and low costs, and is suitable for commercial applications. The n-type conjugated polymer of the present invention has excellent electron transport capability, higher conductivity, and better electromagnetic wave shielding effect. The n-type conjugated polymer of the present invention is applied to an organic optoelectronic device, and can achieve an excellent photoelectric effect.
