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 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...
Synthesis and characterization of conducting block copolymers of thiophene-ended polystyrene with polypyrrole
Alkan, S; Toppare, Levent Kamil; Hepuzer, Y; Yagci, Y (2001-03-15)
4,4' Azobis 4-cyano3-thiophenemethyl pentanate (ACTMP) was synthesized from 3-Thiophenemethanol and 4,4'-Azobis (4-cyanopentanoyl chloride). ACTMP was further used in the synthesis of polystyrene with thiophene terminal groups (TPSt) at both ends. Conducting block copolymers of TPSt and pyrrole (TPSt/PPy) were electrochemically prepared using several supporting electrolytes. Characterization of these block copolymers were performed.
