Title:
POLYTHIOPHENE CONJUGATED POLYMER CONTAINING ELECTRON-WITHDRAWING SUBSTITUENT, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/151675
Kind Code:
A1
Abstract:
A polythiophene conjugated polymer containing an electron-withdrawing substituent, a preparation method therefor, and the use thereof. The structural formula of the polymer is as represented by formula I. The preparation method comprises: under the protection of an inert atmosphere, dissolving a dibromo monomer, a bis-trialkyltin monomer, a palladium catalyst and a ligand in an organic solvent; and carrying out a Stille polymerization reaction under the conditions of darkness and heating to reflux, so as to obtain a polythiophene conjugated polymer containing an electron-withdrawing substituent. Further provided is the use of the polythiophene conjugated polymer, which contains the electron-withdrawing substituent and is represented by formula I, in an organic field effect transistor as an electron transport material, and the use of the polythiophene conjugated polymer as an n-type high-molecular thermoelectric material.
