2-(N-pyrrolyl)ethylvinyl ether (2-NEVE) was synthesized from 2-chloroethylvinyl ether (2-CEVE) via a phase catalysis reaction. Cyclic voltammetric studies were carried out to check for the electroactivity of 2-NEVE. Poly(2-(N-pyrrolyl)ethylvinyl ether) [poly(2-NEVE)] was synthesized via chemical methods. Graft copolymers of pyrrole and 2-NEVE were synthesized by electrochemical methods. The chemical structures of 2-NEVE and poly(2-NEVE) were investigated by several spectroscopic methods. Graft copolymers were characterized by means of FTIR, scanning electron microscopy (SEM). differential scanning calorimetry (DSC), and thermal gravimetric analysis (TGA). The conductivities of the graft copolymers were measured via a four-probe technique.

Synthesis and characterization of a bifunctional amido-thiophene monomer and its copolymer with thiophene and electrochemical properties AK, M; Çırpan, Ali; Yılmaz, Fatih; YAGCI, Y; Toppare, Levent Kamil (2005-05-01) A bifunctional amido-thiophene namely hexamethylene (bis-3-thiophene acetamide) (HMTA) was synthesized by the reaction of 3-thiophene acetic acid with hexamethylene diamine. Copolymerization in the presence of thiophene was achieved electrochemically in tetrabutylammonium tetrafluoroborate/acetonitrile (TBAFB/AN). Spectroelectro-chemical analysis of the resulting copolymer [P(HMTA-co-Th)] reflected electronic transitions at 505 nm, 740 nm and similar to 1000 nm, revealing pi to pi* transition, polaron and b...
Synthesis of block copolymers by combination of photoinduced and atom transfer radical polymerization routes Erel Göktepe, İrem; Serhatli, Ersin; Yağcı, Yusuf (2002-01-01) Block copolymers of methyl methacrylate (MMA) and styrene (St) were obtained by the combination of two different free radical polymerization processes, namely photoinduced and atom transfer radical polymerization (ATRP) methods. In the first step, hydroxy terminated polymers were prepared by photoinitiated polymerization of MMA in the presence of N,N'-dimethylethanolamine and benzophenone as the initiating system and subsequently converted to bromine ended poly(methyl methacrylate) by the esterification of ...
Synthesis and characterization of graft copolymers of poly(2-(N-pyrrolyl)ethylvinylether) and polypyrrole Kalaycioglu, E; Toppare, Levent Kamil; Yagci, Y (Elsevier BV, 2000-01-03) Poly(2-(N-pyrrolyl)ethylvinylether) (poly(2-NEVE)) was synthesized from poly(2-chloroethylvinylether) (poly(2-CEVE)) via phase catalysis reaction. Graft copolymers of PPy/poly(2-NEVE) were synthesized by electrochemical methods. The chemical structure of poly(2-NEVE) was investigated by several spectroscopic and thermal methods. Graft copolymers were characterized by means of FTIR, Differential Scanning Calorimetry (DSC), Thermal Gravimetry Analysis (TGA), Scanning Electron Microscope (SEM). Conductivities ...
Synthesis and characterization of conducting copolymers of menthyl ester of 3-thiophene acetic acid with pyrrole Kiralp, S; Alkan, S; Toppare, Levent Kamil; Cianga, I; Yagci, Y (2003-01-01) 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.
Synthesis of 1,2,3,5- tetrasubstituted pyrrole derivatives via 5-exo-dig type cyclization and stereoselective functionalisation of ferrocene derivatives Kayalar, Metin; Demir, Ayhan Sıtkı; Department of Chemistry (2005) A convenient and new method for the synthesis of 1,2,3,5-tetrasubstituted pyrrole derivatives starting from 1,3,-dicarbonyl compounds through acid catalyzed cyclization reaction is described. Alkylation of 1,3-dicarbonyl compound with propargyl bromide followed by one step cyclization with the introduction of primary amines in the presence of catalytic amount of triflouroacetic acid (TFA) affords the corresponding pyrrole derivatives in high yields. The investigations on the studies of developing a new meth...
