Three new donor-acceptor-donor (DAD) type monomers containing five membered heteroaromatic rings as the donor units and the silicon-bridged bithiophene as the acceptor unit were synthesized via Stille cross-coupling reaction. The monomers, 2,6-di(furan-2-yl)-4,4-dioctyl-4H-silolo[3,2-b:4,5-b'] dithiophene (FSiF), 4,4-dioctyl-2,6-di(thiophen-2-yl)-4H-silolo[3,2-b:4,5-b']dithiophene (TSiT) and 4,4-dioctyl-2,6-di(selenophen-2-yl)-4H-silolo[3,2-b:4,5-b'] dithiophene (SeSiSe) were polymerized electrochemically via potential cycling in acetonitrile-tetrabutylammonium perchlorate electrolytic medium. Optical and electrochemical properties of the monomers and their corresponding polymers were investigated and it was found that oxidation potentials of the monomers and optical properties of both monomers and their polymers showed slight variations depending on the heteroatom present in the donor unit.

Synthesis and Characterization of Thiophene and Thieno[3,2-b]thiophene Containing Conjugated Polymers Rustamh, Elvin; Goker, Seza; UDUM, YASEMİN; Udum, Yasemin Arslan; Toppare, Levent Kamil (The Electrochemical Society, 2015-01-01) Herein, we report the synthesis of two donor-acceptor-donor polymers (P1 and P2) based on thiophene (M1) and thieno [3,2-b]thiophene (M2) as the donor and 2,5-bis(dodecyloxy)benzene as the acceptor unit. The effects of different donor units on the polymers' electrochemical and optical properties were examined by cyclic voltammetry and spectroelectrochemical analysis. Introducing thieno[3,2-b]thiophene unit as the donor unit enhances pi-stacking and consequently lowering the bandgap of the resulting polymer....
Synthesis of New Thienylene Pyrrole Monomers and Their Electropolymerizations Eken, Serap; Carbas, Buket Bezgin; Akdağ, Akın; Önal, Ahmet Muhtar (The Electrochemical Society, 2014-01-01) In this study, four new 2,5-dithienylpyrroles (SNS) 1-(3-fluoro-phenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (m-FPTP), 1-(3-chlorophenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (m-ClPTP), 1-(3-bromo-phenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (m-BrPTP) and 1-(4-bromo-phenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (p-BrPTP) containing meta and para substituted benzene ring at the nitrogen atom were synthesized via Paal-Knorr condensation of 1,4-di(2-thienyl)-1,4-butanedione with corresponding halo-substituted anilines. The mon...
Investigation of Fluorine Atom Effect on Benzothiadiazole Acceptor Unit in Donor Acceptor Donor Systems Çakal, Deniz; Akdağ, Akın; Önal, Ahmet Muhtar (The Electrochemical Society, 2019-07-12) Synthesis of two new pi-conjugated monomers containing fluorine substituted benzothiadiazoles as acceptor units and 3,4-ethylenedioxythiophene (EDOT) as donor unit was accomplished by facilitating Stille cross-coupling reactions (4,7-bis(2,3-dihydrothieno[3,4-b][1,4] dioxin-5-yl)-5-fluorobenzo[c][1,2,5] thiadiazole (E2BTD-F) and 4,7-bis(2,3-dihydrothieno [3,4-b][1,4] dioxin-5-yl)-5,6-difluorobenzo[c][1,2,5] thiadiazole (E2BTD-2F)). NMR and HRMS spectra of newly synthesized compounds are in agreement with th...
Efficient Ceria-Supported Rhodium Nanoparticles as an Electrocatalyst for Hydrogen Evolution Akbayrak, Merve; Önal, Ahmet Muhtar (The Electrochemical Society, 2019-12-13) Rh-0/CeO2 catalystwas prepared by the reduction of Rh+3 ions on CeO2 surface and characterized by transmission electron microscopy, inductively coupled plasma optical emission spectrometry, X-ray photoelectron spectroscopy and powder X-ray diffractometry techniques. To investigate its electrocatalytic activity for H-2 evolution reaction, a glassy carbon electrode (GCE) was modified with Rh-0/CeO2. The modified electrode was found to exhibit a high electrocatalytic activity (turnover frequency (TOF): 1.56 s(...
The effect of the donor unit on the optical properties of polymers UNVER, Elif Kose; TARKUC, Simge; Udum, Yasemin Arslan; Tanyeli, Cihangir; Toppare, Levent Kamil (Elsevier BV, 2011-10-01) A series of donor-acceptor-donor (DAD) type pi-conjugated monomers containing 10,11,12,13-tetrahydrodibenzo[a, c] phenazine moiety in the backbone as the acceptor unit and thiophene derivatives as the donor unit were prepared by Stille coupling. Thiophene, 3-hexyl thiophene and 3,4-ethylenedioxythiophene were used as the donor units to understand the effects of donor unit on electrochemical and optoelectronic properties of the resulting polymers. Electroactivity of monomers and redox behavior of their polym...
