Copolymer of 1-(4-nitrophenyl)-2,5-di(2-thienyl)-1H-pyrrole (NTP) with 3,4-ethylene dioxythiophene (EDOT) was electrochemically synthesized and characterized. Resulting copolymer film has distinct electrochromic properties. It has five different colors (light red, red, light grey, green, and blue). At the neutral state lambda(max) x value due to the pi-pi* transition was found to be 550 nm and E-g was calculated as 1.6 eV. Double potential step chronoamperometry experiment shows that copolymer film has good stability, fast switching time (1.2 s) and high optical contrast (42%).

A soluble conducting polymer of 4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)benzenamine and its multichromic copolymer with EDOT YİLDİZ, Ersin; ÇAMURLU, PINAR; Tanyeli, Cihangir; AKHMEDOV, Idris; Toppare, Levent Kamil (2008-01-15) Here we report the synthesis of a monomer, 4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)benzenamine (SNS-NH2) produced by the reaction of 1,4-di(2-thienyl)-1,4-butanedione and benzene-1,4-diamine. This monomer was electrochemically polymerized in the presence of LiClO4, NaClO4 (1:1) as the supporting electrolyte in acetonitrile. Copolymerization in the presence of 3,4-ethylenedioxythiophene (EDOT) was achieved in acetonitrile NaClO4/LiClO4 (0.1 M:0.1 M) solvent-electrolyte couple. Resulting homopolyrner and copo...
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...
A soluble conducting polymer: 1-Phenyl-2,5-di(2-thienyl)-1H-pyrrole and its electrochromic application Tarkuc, S.; Sahmetlioglu, E.; Tanyeli, Cihangir; Akhmedov, I. M.; Toppare, Levent Kamil (2006-07-28) A thiophene-functionalized monomer 1-phenyl-2,5-di(2-thienyl)-1H-pyrrole (PTP) was synthesized. The chemical polymerization of PTP (CPTP) was realized by using FeCl3 as the oxidant. The structures of both the monomer and the soluble polymer (CPTP) were investigated by Nuclear Magnetic Resonance (H-1 and C-13 NMR) and Fourier Transform Infrared (FTIR). The average molecular weight of the chemically synthesized polymer was determined by gel permeation chromatography (GPC) as Mn = 7.2 x 10(3). The electrochemi...
Conducting graft copolymers of pyrrole and thiophene with random copolymers of methyl methacrylate and 3-methylthienyl methacrylate Guner, Y; Toppare, Levent Kamil; Hepuzer, Y; Yagci, Y (2004-08-01) Random copolymers of 3-methyl thienylmethacrylate and methyl methacrylate were synthesized via free radical polymerization. Electro-copolymerizations of random copolymers with thiophene and/or pyrrole were carried out in acetonitrile-tetrabutylammonium tetrafluoroborate (TBAFB), water-p-toluene sulfonic acid (PTSA) solvent-electrolyte couples. Oxidative polymerization of thiophene functionalized random copolymer was also achieved by constant current electrolysis and chemical polymerization. The characteriza...
A novel conducting polymer based on terthienyl system bearing strong electron-withdrawing substituents and its electrochromic device application Asil Alptekin, Demet; Algı, Fatih; Önal, Ahmet Muhtar (Elsevier BV, 2008-7) A novel conducting polymer bearing strong electron-withdrawing substituents (EWS) directly attached to the 3,4-positions of the thiophene ring was synthesized by electrochemical polymerization of diethyl 2,5-di(thiophen-2-yl)thiophene-3,4-dicarboxylate (SSS-Diester). The polymer (PSSS-Diester) was characterized by cyclic voltammetry, FT-IR and UV-vis spectroscopy. The polymer has a reversible redox process and demonstrates a stable electrochromic behavior: reddish orange in the neutral state, brown in the i...
