“…Hu et al. reported a novel copolymer based on EDOT and oligo (oxyethylene) cross‐linked 2,2′‐bithiophene, the corresponding films exhibited freestanding state and better stability compared with the homopolymers . Moreover, we also synthesized a novel crosslinking PEDOT derivative based on two EDOT units bridged by alkoxy chain, 1,6‐bis((2,3‐dihydrothieno[3,4‐ b ][1,4]dioxin‐2‐yl)methoxy)hexane (BEDTH) .…”

Three random copolymers PE- co -M1 , PE- co -M2 , and PE- co -M3 were obtained by electrochemical polymerization of donor–acceptor–donor monomers M1 , M2 , and M3 with 3,4-ethylenedioxythiophene moiety, respectively, using a 1:1 molar ratio of the corresponding monomers, to find new properties and a more effective way to control the optoelectronic properties in conjugated system. For comparison purpose, polymers P1 , P2 , and P3 were prepared from the corresponding monomer units M1 – M3 , respectively, by electrochemical polymerization. We also present efficient synthesis, characterization, and comparative density functional theory (DFT) calculations of the monomers M1 – M3 and polymers P1 – P3 . Cyclic voltammetry, spectroelectrochemistry, and electrochromic properties of all of the polymers P1 – P3 and copolymers PE- co -M1 , PE- co -M2 , and PE- co -M3 were carried out and a throughout comparison was made. We have shown that electrochemical copolymerization is a powerful strategy to tune the highest occupied molecular orbital energy level, band gap, and color of the copolymer. Thus, this finding clearly indicates that the copolymers show significantly different optoelectronic properties compared to their constituent polymers.

“…22 OEG attached on thiophene polymers has been employed as an electrochromic material with multiple colors. 24,25 As a thermoelectric material, the OEG side-chain also has a significant effect on the thermoelectric property compared with the alkyl group. 26 The OEG as a side-chain allows for good optical transparency, processability, and environmental stability as well as high dispersion of polymers in organic solvents.…”

Conductive thiophene-based polymers have garnered great attention for use in organic electron materials such as electrochromic and thermoelectric materials. However, they suffer from poor electron transport properties and long-term stability, leading to limited development eventually. Here, we proposed a strategy of functionalized thiophene-based polymers with oligo(ethylene glycol) or alkyl side chains and synthesized a series of poly(3,4-ethylenedioxy bithiophene)s (PEDTs) to tune their electrochromic and thermoelectric properties. An alkyl group bearing electronic ability at the thiophene ring effectively achieved a large increase in the electrical conductivity with nearly invariable Seebeck coefficient, resulting in an enhancement by 1 order of magnitude for the thermoelectric power factor. Moreover, the electrochromic properties of functionalized PEDTs gained an effective improvement in the optical contrast and coloration efficiency as well as stability with multicolor changes between neutral and oxidized states. The functionalized PEDTs can be proposed as an alternative strategy to tune the electrochromic and thermoelectric properties for organic polymer materials.
