Journal ArticleDOI
Electrochemical and XPS studies toward the role of monomeric and polymeric sulfonate counterions in the synthesis, composition, and properties of poly(3,4-ethylenedioxythiophene)
Gianni Zotti,Sandro Zecchin,Gilberto Schiavon,Frank Louwet,L. Groenendaal,Xavier Crispin,Wojciech Osikowicz,William R. Salaneck,Mats Fahlman +8 more
TL;DR: In this paper, the authors compared electrochemically prepared poly(3,4-ethylenedioxythiophene) (PEDT) poly(styrenesulfonate) (PSS), produced from acidic (PSSH) and basic (PSSNa) PSS, was characterized by cyclic voltammetry CV, UV−vis spectroscopy, in situ conductivity, and XPS analysis.
Journal ArticleDOI
Electrochemical, Conductive, and Magnetic Properties of 2,7-Carbazole-Based Conjugated Polymers
TL;DR: In this article, the authors investigated the in-situ conductivity of poly(2,7-carbazole)s and showed that the presence of a strong electron-withdrawing substituent onto the nitrogen atom in the homopolymer leads to an increase by 3 orders of magnitude of the conductivity.
Journal ArticleDOI
New Low-Gap Polymers from 3,4-Ethylenedioxythiophene-Bis-Substituted Electron-Poor Thiophenes. The Roles of Thiophene, Donor−Acceptor Alternation, and Copolymerization in Intrinsic Conductivity
Anna Berlin,Gianni Zotti,Sandro Zecchin,and Gilberto Schiavon,Barbara Vercelli,Alberto Zanelli +5 more
TL;DR: In this paper, a low-gap thiophene-based regular copolymers are produced by anodic coupling of 3,4-ethylenedioxythiophene (2,5-substituted thieno[3,4b]pyrazine (TP), cyclopenta[2,1-b;3, 4-b]dithiophen-4-one (CO), and 4-dicyanomethylene-4H-cyclopenta(CN).
Journal ArticleDOI
Synthesis and Thermoelectric Properties of Polycarbazole, Polyindolocarbazole, and Polydiindolocarbazole Derivatives
Isabelle Lévesque,‡ Pier-Olivier Bertrand,Nicolas Blouin,Mario Leclerc,Sandro Zecchin,Gianni Zotti,Christopher I. Ratcliffe,D. D. Klug,Xing Gao,and Faming Gao,John S. Tse +10 more
TL;DR: The best combination of Seebeck coefficient and conductivity was around 10-7 W m-1 K-2 with copolymers comprising thiophene units alternating with carbazole or indolocarbazole as mentioned in this paper.
Journal ArticleDOI
Chemical and electrochemical synthesis and characterization of polydiphenylamine and poly-N-methylaniline
TL;DR: The conductivity of polydiphenylamine (3 × 10 −2 Ω −1 cm −1 ) increases when polymerization is performed in acetonitrile, in which n increases to 10 −11.5.
