Journal ArticleDOI
Crown‐Tetrathiafulvalenes Attached to a Pyrrole or an EDOT Unit: Synthesis, Electropolymerization and Recognition Properties
Gaëlle Trippé,Franck Le Derf,Joel Lyskawa,Miloud Mazari,Jean Roncali,Alain Gorgues,Eric Levillain,Marc Sallé +7 more
TL;DR: These electrodes constitute the first examples of conducting polymer-based modified electrodes incorporating a TTF electrochemical probe, able to interact with a guest ion, such as Ba2+.
Journal ArticleDOI
Structural Control of the Reversible Dimerization of π-Conjugated Oligomeric Cation Radicals
Eric Levillain,Jean Roncali +1 more
TL;DR: The reversible dimerization of the electrochemically or chemically generated cation radicals of diversely substituted tetrathienylenevinylenes (1−6) has been analyzed by concentration and temperature-dependent cyclic voltammetry, UV−vis, near-IR, and ESR spectroscopies, and time-resolved spectroelectrochemistry.
Journal ArticleDOI
Chain Length Dependence of the Photovoltaic Properties of Monodisperse Donor–Acceptor Oligomers as Model Compounds of Polydisperse Low Band Gap Polymers
Cheng Zhou,Yamin Liang,Feng Liu,Chen Sun,Xuelong Huang,Zengqi Xie,Fei Huang,Jean Roncali,Thomas P. Russell,Yong Cao +9 more
TL;DR: In this article, the authors show that the edge-on orientation of short-chain systems evolves toward a face-on orientation as chain length increases while the π-stacking distance decreases beyond 7 units.
Journal ArticleDOI
3,4-Phenylenedioxythiophene (PheDOT): a novel platform for the synthesis of planar substituted π–donor conjugated systems
Sophie Roquet,Philippe Leriche,Igor F. Perepichka,Bruno Jousselme,Eric Levillain,Pierre Frère,Jean Roncali +6 more
TL;DR: In this paper, a benzenic analogue of 3,4-ethylenedioxythiophene (EDOT) has been synthesized using two different routes, namely, etherification of 2,5-dicarboethoxy-3, 4-dihydroxythiophenes with halo-aromatics and transetherification of 3-4-dimethoxythiophemes with catechols.
Journal ArticleDOI
Polarizability and internal charge transfer in thiophene-triphenylamine hybrid π-conjugated systems.
TL;DR: Extended star-shaped conjugated systems consisting of dicyanovinyl electron-acceptor units connected to a triphenylamine core by means of thiophene, thienylenevinylene, and bithiophene conjugating spacers have been synthesized.
