A new thiophene derivative containing menthyl group (MM) was synthesized and polymerized via chemical and electrochemical (constant current) methods. Polymers obtained and MM itself were used to synthesize copolymers with pyrrole under conditions of constant potential electrolyses. Cyclic voltammetry (CV), thermal analysis (DSC, TGA) and scanning electron microscopy (SEM) analyses were performed for the characterization of samples.

Taşkın, Aslı Tuba; Toppare, Levent Kamil; Department of Chemistry (2009)
A novel electroactive monomer 5,8-Di(1H-pyrrol-2-yl)-2, 3-di(thiophen-2-yl) quinoxaline (PTQ) was successfully synthesized via Stille Coupling reaction between quinoxaline and pyrrole. Nuclear magnetic resonance (1H NMR and 13C NMR) and Mass spectroscopy were used to characterize the monomer. The monomer was electrochemically polymerized in the presence of tetrabutylammonium perchlorate (TBAP) as supporting electrolyte in dichloromethane. Monomer reveals relatively low oxidation potential at +0.70V. Spectro...
Characterization of the polymer of a dipyrrolyl monomer by pyrolysis mass spectrometry
Ertas, Merve; Hacaloğlu, Jale; Toppare, Levent Kamil (2004-08-01)
In this work, characterization of a homopolymer of succinic acid bis(4-pyrrol-1-ylphenyl) ester prepared by galvonastatic polymerization was carried out by direct pyrolysis mass spectrometry. Although decomposition of the monomer yielding mainly butadionic acid and pyrrole occurred under the galvonastatic polymerization conditions, growth of the polymer through the pyrrole moieties was also achieved, yielding a ladder-type polymer film. The polypyrrole chains contained both quinoid and aromatic units as in ...

A new polythiophene derivative was synthesized by both chemical and electrochemical oxidative polymerization of 1-(perfluorophenyl)-2,5-di(2-thienyl)-1H-pyrrole (FPTPy). The structures of both the monomer and the soluble polymer were elucidated by nuclear magnetic resonance (H-1-NMR) and fourier transform infrared (FTIR). Polymer of FPTPy was also synthesized via potentiostatic electrochemical polymerization in acetonitrile (AN)/NaClO4/LiClO4 (0.1 M:0.1 M) Solvent-electrolyte couple. Characterizations of th...
Characterization of conducting copolymers of succinic acid bis-(-4-pyrrol-1-yl-phenyl) ester and thiophene via pyrolysis mass spectrometry
Ertas, Merve; Hacaloğlu, Jale; Toppare, Levent Kamil (2005-03-01)
In this work, a direct pyrolysis mass spectrometry technique was applied to characterize a conducting copolymer of succinic acid bis-(4-pyrrol-1-yl-phenyl) ester (SM) and thiophene prepared by electrochemical polymerization. Thermal degradation behavior of both components was quite similar to those of the corresponding homopolymers, PSM, and polythiophene PTh. Yet, detection of oligomers and mixed dimers of both monomers in the high temperature pyrolysis mass spectra confirmed the formation of a copolymer. ...
