Electrochromic properties of a soluble conducting polymer of 1-benzyl-2,5-di(thiophene-2-yl)-1H-pyrrole

Processable electrochromic and fluorescent polymers based on N-substituted thienylpyrrole

“…For example, Ferraris et al obtained soluble and conducting polymers via either electrochemical or chemical oxidation of ␣-linked thienylpyrrole ring systems with alkyl substituents on the ␤-position of the central pyrrole ring [9]. The following studies of Ferraris et al and Toppare et al mainly focused on the elucidation of both electrochemical and optical properties of N-substituted polythienylpyrroles [10][11][12][13][14][15][16][17][18][19].…”

N-substituted 2,5-di(2-thienyl)pyrroles: application, production, properties, and electrochemical polymerization (review)

“…Using the Paal-Knorr method the authors of [43][44][45][46][47][48] synthesized and investigated the N-substituted 2,5-di(2-thienyl)pyrroles 14-18. Compound 15 had been obtained earlier by the same synthetic approach [49], and its crystal structure was described in [50].…”

“…By a method similar to the method described in [43][44][45][46][47][48] a group led by G. G. Abashev obtained compounds 21-24 [55,56] The heterocycle 23, containing four thiophene rings, polymerizes best of all, although the peak for the formation of the radical-cation under the chosen conditions has a fairly high value (E a = 0.89, E onset ~ 0,7 V). In compound with the Gewald thiophene residue the radical-cation is formed at a substantially lower potential, E a = 0.65 V, but the polymerization of this heterocycle is not vigorous.…”

Synthesis, Characterization and Optoelectrochemical Properties of Poly(2,5-di(thiophen-2-yl-)1-(4-(thiophen-3-yl)phenyl)-1H-pyrrole-co-EDOT)

“…Many applications of conjugated polymers, such as light emitting electrochemical cells [7,8], microactuators [9,10], energy storage [11], photovoltaic [12] and electrochromic devices (ECDs) [13][14][15], and sensors [16] are based on electrochemical transition between doped and neutral states or rely on the stability of a specific doping level.…”
