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.

An organic photovoltaic device includes an anode and a cathode. The organic photovoltaic device includes an active layer between the anode and the cathode. The active layer includes a p-type material. The p-type material includes a donor-acceptor (DA) polymer. An acceptor unit of the DA polymer includes a functionalized pyranopyran-dione compound or a functionalized naphthyridine-dione compound.

A novel monomer design for the synthesis of PPE-type polymers containing conjugated segments of well-defined length connected by flexible linkers under Sonogashira reaction conditions is presented. The resulting polymers retain the photophysical properties of a fully conjugated PPE. The extent of incorporation of the flexible units along the backbone is governed by the comonomer feed ratio and can be varied in a statistically predictable fashion.
