In this study electrochemical copolymerization of 1-(perfluorophenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole and 3,4-ethylenedioxythiophene was used to fulfill a strategy in achieving desired multichromic properties. The resultant polymer displayed distinct color changes between red-violet, amber, green and blue color with good switching times and optical contrast. A direct correlation between the color of the polymer in neutral state and the applied potential during synthesis was observed. Hence, it was possible to achieve colors from maroon, red-violet, and eggplant to indigo depending on the applied potential. A dual type electrochromic device of the copolymer and poly(3,4-ethylenedioxythiophene) was constructed to evaluate the possible use of such copolymer in device applications. The device displayed multichromism, with 1.1 s switching time and good electrochromic memory.

Study on mechanical properties of perlite-filled gamma-irradiated polypropylene
Akin-Oktem, G; Tanrisinibilir, S; Tincer, T (Wiley, 2001-09-12)
This study covers the preparation and characterization of perlite-filled polypropylene (PP). The compositions of 15, 30, and 50 % by weight perlite-PP composites were prepared by melt-mixing. The PP used in this study was either applied in the virgin form or gamma -irradiated in air at the doses of 10, 25, 50, and 100 kGy to determine the effect of oxidative degradation in composite properties. Furthermore, the active sites containing oxygen produced by gamma -irradiation in PP may provide a possible enhanc...
Enhancing electrochemical and electrochromic performances of carbazole comprising monomer via copolymerization with 3,4-ethylenedioxythiophene (EDOT)
Kalay, Isil; Yigit, Deniz; GÜLLÜ, Mustafa; DEPCİ, TOLGA; Toppare, Levent Kamil; Hacioglu, Serife O. (Elsevier BV, 2020-09-01)
In this study, two novel electrochromic copolymers (CoP1.3 and CoP1.5) were synthesized via electrochemical methods and characterized. The comonomers used in the synthesis were 3,4-ethylenedioxythiophene (EDOT) and a carbazole comprising monomer; 9-(2-(4-(Phenyldiazenyl) phenoxy) ethyl)-3,6-di(thiophen-2-yl)-9H-carbazole (M1). Carbazole containing monomer (M1) and EDOT were combined with two different comonomer feed ratios, 1: 3 and 1: 5 respectively in order to investigate the effect of increasing EDOT amo...
Electrochromic properties of a soluble conducting polymer of 1-benzyl-2,5-di(thiophene-2-yl)-1H-pyrrole
Tarkuc, S.; Sahmetlioglu, E.; Tanyeli, Cihangir; Akhmedov, I. M.; Toppare, Levent Kamil (Elsevier BV, 2007-02-20)
In this study, synthesis of a thiophene functionalized monomer, 1-benzyl-2,5-di(thiophene-2-yl)-1H-pyrrole (SNBS) was achieved. A new polythiophene derivative was synthesized by both chemical and electrochemical polymerization. The polymer synthesized via chemical oxidative method was soluble in organic solvents and characterized by nuclear magnetic resonance (H-1 and C-13 NMR) spectroscopy. The average molecular weight of the chemically synthesized polymer was determined by gel permeation chromatography (G...
Electrochemical Synthesis of Poly(methylsilyne) and Investigation of the Effects of Parameters on the Synthesis
EROĞLU PALA, DAMLA; Nur, Yusuf; Bayram, Göknur; Toppare, Levent Kamil (Wiley, 2010-12-05)
This study aims to synthesize poly(methylsilyne) by electrochemical reduction of methyltrichlorosilane at a constant potential of -6 V, while investigating the effects of parameters such as the nature of the electrode, solvent and supporting electrolyte, the monomer/solvent ratio, and the reaction time on the properties of the products. The polymer was characterized by H-1-NMR (Proton Nuclear Magnetic Resonance Spectroscopy), FTIR (Fourier Transform Infrared Spectroscopy), UV-Visible Spectroscopy, and TGA (...
Immobilization of invertase in conducting polypyrrole/PMMA-co-PMTM graft copolymers
Yildiz, HB; Kiralp, S; Toppare, Levent Kamil; Yagci, Y (Wiley, 2005-04-15)
In this study, invertase was immobilized in copolymer electrodes constructed. Three different types of polymethyl methacrylate-co-polymethyl thienyl methacrylate matrices were used to obtain copolymers that were characterized by FT-IR spectroscopy. Immobilization of enzymes was carried out by the entrapment of the enzyme in conducting polymer matrices during electrochemical polymerization of pyrrole through thiophene moieties of polymers. Immobilization of the enzyme was achieved by application of 1.0 V con...
