Title:
3,4-ETHYLENEDIOXYTHIOPHENE POLYMER CAPABLE OF BEING SUPER-ASSEMBLED WITH CARBON-BASED MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/244609
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of organic supermolecules, and specifically relates to a 3,4-ethylenedioxythiophene polymer capable of being super-assembled with a carbon-based material and a preparation method therefor. The polymer of the present invention is a high-molecular polymer with 3,4-ethylenedioxythiophene-2-acetylene as a main chain and an alkoxy group as a side chain. The preparation method therefor involves using 3,4-ethylenedioxythiophene as a starting material, first subjecting same to a bromination reaction to obtain 2,5-dibromo-3,4-vinyldioxythiophene, then reacting same with trimethylsilylacetylene to obtain a bistrimethylsilyl-3,4-vinyldioxythiophene intermediate, and after removal of a TMS protecting group, subjecting same with 2,5-dibromo-3,4-vinyldioxythiophene to an Sonogashira reaction, so as to obtain the 3,4-ethylenedioxythiophenyl high-molecular polymer. A superassembly system with main chain π-π adsorption and a side chain winding can be formed between the polymer of the present invention and a carbon nanotube, and the 3,4-vinyldioxythiophene polymer/carbon nanotube complex formed by the superassembly system has good stability, and has a wide application prospect in composite materials.
