The present invention belongs to the technical field of organic supermolecules, and specifically discloses a 3,4-ethylenedioxythiophene (EDOT) polymer capable of supramolecular assembly with carbon-based materials, and a preparation method thereof. The polymer of the present invention is a polymer with 3,4-ethylenedioxythiophene-2-acetylene as the main chain and alkoxy as the side chain. The polymer is prepared as follows: subjecting EDOT to bromination, to give 2,5-dibromo-3,4-ethylenedioxythiophene; then reacting 2,5-dibromo-3,4-ethylenedioxythiophene and trimethylsilyl acetylene (TMSA) to give bis(trimethylsilyl)-3,4-ethylenedioxythiophene; removing trimethylsilyl (TMS) protecting groups from the bis(trimethylsilyl)-3,4-ethylenedioxythiophene, and subjecting the obtained compound and 2,5-dibromo-3,4-ethylenedioxythiophene to Sonogashira coupling to give an EDOT polymer. The polymer of the present invention can form a supramolecular assembly system with carbon nanotubes (CNTs), which involves π-π adsorption of the main chain and entanglement of the side chain.
