A new polythiophene derivative was synthesized by electrochemical oxidative polymerization of 2,5-di( thiophen-2-yl)-1-(4-(thiophen-3-yl) phenyl)-1H-pyrrole (TTPP). The structure of the monomer was evaluated by H-1-NMR and FT-IR. The polymer (P(TTPP)) and its co-polymer with 3,4-ethylenedioxythiophene (P(TTPP-co-EDOT)) were synthesized via potentiostatic electrochemical polymerization. The resulting polymers were characterized by cyclic voltammetry (CV), FT-IR, SEM and UV-Vis spectroscopy, and conductivity measurements. Also, the spectroelectrochemical and electrochromic properties of P(TTPP-co- EDOT) were investigated. While P(TTPP) reveals no electrochromic activity, its co-polymer with EDOT has two different colours (yellow and blue). Optical contrast, switching time, lambda(max) and band gap (E-g) of (P(TTPP-co-EDOT)) were determined. (C) Koninklijke Brill NV, Leiden, 2010

Synthesis and characterization of thiophen-3-yl acetic acid 4-pyrrol-1-yl phenyl ester and its conducting polymers BINGÖL, Bahar; GÜNER, Yusuf; Çırpan, Ali; Toppare, Levent Kamil (Informa UK Limited, 2005-08-01) Thiophen-3-yl acetic acid 4-pyrrol-1-yl phenyl ester (TAPE) monomer was synthesized via reaction of thiophen-3-yl acetyl chloride with 4-pyrrol-1-yl phenol. Homopolymers were achieved by using electrochemical and chemical polymerization techniques. Copolymers of TAPE with bithiophene or pyrrole were synthesized by potentiostatic electrochemical polymerization in acetonitrile-tetrabutylammonium tetrafluoroborate (TBAFB) solvent-electrolyte couple. The chemical structures were confirmed by both Nuclear Magnet...
Synthesis and mesophase properties of block and random co-polymers of electroactive and liquid crystalline monomers Yilmaz, F; Kasapoglu, F; Hepuzer, Y; Yagci, Y; Toppare, Levent Kamil; Fernandes, EG; Galli, G (Informa UK Limited, 2005-01-01) Homo-polymers and random co-polymers of electroactive and liquid crystalline monomers, namely 3-thienylmethyl methacrylate (MTM) and 6-(4-cyanobiphenyl-4'-oxy)hexyl acrylate (LC6), were prepared by conventional free radical polymerization. Block co-polymers of MTM and LC6 were also synthesized by using the 1,1-diphenylethene (DPE) method. The obtained random and block co-polymers exhibited liquid crystal behavior depending on the content of the LC6 units. It was found that microphase separation of the polym...
Synthesis, characterization and optoelectrochemical properties of poly(1,6-bis(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)hexane) and its copolymer with EDOT Ak, Metin; Sahmetlioglu, Ertugrul; Toppare, Levent Kamil (Elsevier BV, 2008-09-01) A new polythiophene derivative was synthesized by electrochemical oxidative polymerization of 1,6-bis(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)hexane (TPH). The structure of the monomer was elucidated by H-1, C-13, MR and mass analyses. The polymer P(TPH) and its copolymer with 3,4-ethylenedioxythiophene (P(TPH-co-EDOT)) were synthesized via potentiostatic electrochemical polymerization. Characterizations of the resulting polymers were performed by cyclic voltammetry (CV), FTIR, UV-vis spectroscopies; and condu...
