Intramolecular CH/π interactions in alkylaromatics: Monomer conformations for poly(3‐alkylthiophene) atomistic models

“…Although the wide majority of the crystal structures of alkylthiophene oligomers present anti arrangements of the β torsion angles, some cases in which gauche conformations are preferred have been reported. As for polymers, the only crystal structure in which a gauche conformation has been determined so far is poly(3‐( S )‐2‐methylbutylthiophene), which, however, has a branched side chain.…”

Exploring the electrochromic properties of poly(thieno[3,2-b]thiophene)s decorated with electron-deficient side groups

“…The polymer electrochemically obtained from this monomer was electroactive and showed a low band gap comparable to PEDOT (1.74 eV from optical measurements and 1.53 eV from electrochemistry). 26 Recently, our group has designed novel compounds of EDOT-TT-EDOT type, with different attachments of EDOT units to the TT core, i.e. at 2,5-or 3,6-positions of TT.…”

Preparation and characterization of aqueous dispersions of poly(3,4‐ethylenedithiathiophene‐co‐3,4‐ethylenedioxythiophene)/ poly(styrene sulfonate) and their conducting films

“…Poly(3,4‐ethylenedithiathiophene) (PEDTT), as one of the most studied PEDOT analogues, has unique electrical and optical properties and potential applications in the fabrication of rechargeable batteries, sensors, photovoltaic devices, electrochromic devices, polymer‐fullerene devices, and so on 3, 4–23. In the past 20 years, the electrochemical homopolymerization of compounds containing 3,4‐ethylenedithiathiophene (EDTT) units, as listed in Scheme , has been studied in detail 6, 9–11, 16, 18, 20, 22.…”
