Several monosubstituted 3-arylazopyrrole derivatives were synthesized for the first time. The oxidation potentials were correlated to the Hammett constants of the substituents. Cyclic voltammetry studies revealed several interesting, features concerning the new compounds. Electrochemical homopolymerizations as well as copolymerization with pyrrole were performed.

Benzyl substituted benzotriazole containing conjugated polymers: Effect of position of the substituent on electrochromic properties
Yigitsoy, Basak; Karim, S. M. Abdul; Balan, Abidin; Baran, Derya; Toppare, Levent Kamil (Elsevier BV, 2010-12-01)
New classes of EDOT coupled-benzotriazole bearing pi-conjugated monomers containing benzyl units on electron-withdrawing benzotriazole moiety were synthesized. The effect of structural differences on electrochemical and optoelectronic properties of the resulting polymers (PBBTES and PBBTEA) was investigated. The results showed that the insertion of benzyl substituent to benzotriazole from different positions changes the electronic structure of polymer which results in completely different electrochemical an...
Electrochemical preparation and characterization of carbon fiber reinforced poly (dimethyl siloxane)/polythiophene composites: electrical, thermal and mechanical properties
Sankir, M; Kucukyavuz, S; Kucukyavuz, Z (Elsevier BV, 2002-05-10)
A series of polydimethylsiloxane (PDMS)/polythiophene (Pth)/carbon fiber (CF) composites was synthesized by electrochemical polymerization using tetrabutylammoniumtetrafluoroborate (TBAFB) as supporting electrolyte and acetonitrile as solvent. Composites were characterized by TGA, SEM, and mechanical tests and conductivity measurements. Conductivities of composites were in the range of 25 S/cm. SEM studies show that CF were coated by PDMS/Pth matrix and well oriented in the matrix. In mechanical tests it ha...
ELECTRICALLY CONDUCTIVE POLY(METHYL METHACRYLATE-G-PYRROLE) VIA CHEMICAL OXIDATIVE POLYMERIZATION
STANKE, D; HALLENSLEBEN, ML; Toppare, Levent Kamil (Elsevier BV, 1993-03-22)
Methyl methacrylate (MMA) and 2-bromoethyl methacrylate (BEMA) were copolymerized and the reactivity ratios of the monomers were determined. A pyrrole moiety was introduced into the copolymer via polymer analogous reaction and grafting between this molecule and pyrrole was achieved by chemical oxidative polymerization of pyrrole with iron-(III) chloride. Conductivities of 10(-2) S/cm were measured.
Conducting polymers of succinic acid bis-(2-thiophen-3-yl-ethyl)ester and their electrochromic properties
SACAN, L; Çırpan, Ali; CAMURLU, P; Toppare, Levent Kamil (Elsevier BV, 2006-02-01)
The homopolymer and copolymer of succinic acid bis-(2-thiophen-3-yl-ethyl)ester with thiophene were achieved via constant potential electrolysis in the presence of tetrabutylammonium tetrafluoroborate as the supporting electrolyte, and acetonitrile/borontrifluoride ethylether (ACN/BFEE) (10:2 v/v) solvent mixture. The characterizations of both homopolymer (PSATE) and copolymer P(SATE-co-Th) were achieved by various techniques including cyclic voltammetry (CV), Fr-IR, scanning electron microscopy (SEM) and U...
Immobilization of urease in conducting thiophene-capped poly(methyl methacrylate)/pyrrole matrices
Alkan, S; Toppare, Levent Kamil; Bakir, U; Yagci, Y (Elsevier BV, 2001-08-22)
Urease was immobilized in conducting polypyrrole and block copolymers of thiophene-capped poly(methyl methacrylate) matrices by electropolymerization. Immobilization of the enzyme was achieved by application of 1.0 V constant potential in a solution of 0.02 M pyrrole, 2 mg/ml urease, 0.5 mg/ml supporting electrolyte. The optimum immobilization conditions, electrolysis time, electrolysis medium, enzyme concentration during electrolysis, type of supporting electrolyte were determined. The kinetic behaviors of...
