Syntheses and Optical Properties of Perfluorophenyl Containing Benzimidazole Derivatives: The Effect of Donor Units ILERI, Merve; HACIOGLU, Serife O.; Çırpan, Ali; Toppare, Levent Kamil (2015-07-03) Synthesis of two novel donor - acceptor - donor type monomers containing benzimidazole as the acceptor unit and thiophene and 3,4-ethylenedioxythiophene (EDOT) as the donor units were performed. 2-(Perfluorophenyl)-4,7-di(thiophen-2-yl)-1H-benzo[d]imidazole and 4,7-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-2-(perfluorophenyl)-1H-benzo[d]imidazole were synthesized successfully and polymerized electrochemically. The electrochemical and spectroelectrochemical studies of the polymers were studied. The effec...
Syntheses, characterization and optical properties of fluorine containing benzimidazole derivatives İleri, Merve; Toppare, Levent Kamil; Çırpan, Ali; Department of Chemistry (2015) In the last decades use of conducting polymers as electrochromic materials attracted tremendous attention all over the world due to properties like processability, high optical contrasts, fast switching times and tuning band gap via structural modifications. Low band gap polymers are pursued in order to increase the conductivity. For that matter donor – acceptor – donor theory is the most effective and commonly used method. The donor – acceptor – donor approach is not only used for obtaining low band gap po...
Syntheses and Optoelectronic Properties of Quinoxaline Polymers: The Effect of Donor Unit Sendur, Merve; Balan, Abidin; Baran, Derya; Toppare, Levent Kamil (Wiley, 2011-09-15) Tuning the bandgap of electrochromic polymers is one of the important research topics in electrochromism. To understand clearly the effect of donor unit in donor-acceptor-donor-type polymers, 2,3-bis(4-tert-butylphenyl)-5,8-di(thiophen-2-yl)quinoxaline and 2,3-bis(4-tert-butylphenyl)-5-(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-8-(thiophen-2-yl)quinoxaline were synthesized and polymerized potentiodynamically. Their electrochemical and spectroelectrochemical studies were performed, and the results were compa...
Syntheses and investigation of electrochemical properties of selenophene and benzotriazole bearing copolymers Ünay, Hande; Çırpan, Ali; Ünalan, Hüsnü Emrah; Department of Polymer Science and Technology (2014) Polymers containing selenophene as a π bridge; poly(2-(2-octyldodecyl)-4-(selenophen-2-yl)-7-(5-(thiophen-2-yl)selenophen-2-yl)-2H-benzo[d][1,2,3]triazole) (P-SBTTh) and poly(2-(2-octyldodecyl)-4-(5-phenylselenophen-2-yl)-7-(selenophen-2-yl)-2H-benzo[d][1,2,3]triazole (P-SBTPh) were synthesized via Stille and Suzuki coupling, respectively. Optical and electrochemical properties were investigated and comparisons with their thiophene analogs were done. Selenophene substitution resulted in low band gap and red...
Syntheses and characterization of benzimidazole containing polymers: a comparative study on donor unit effect and influence of H-bonding Nurioğlu, Ayda Gökçek; Toppare, Levent Kamil; Department of Chemistry (2013) The first part of this work reports a comparative study on electrochromic properties of two Donor-Acceptor-Donor (DAD) type polymers, namely poly(2-heptyl-4,7-di(thiophen-2-yl)-1H-benzo[d]imidazole) (BImTh) and poly(4,7-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-2-heptyl-1H-benzo[d]imidazole) (BImEd). DAD type polymers are designed to bear the same acceptor unit, benzimidazole and two different donor units, thiophene and 3,4-ethylenedioxy thiophene (EDOT) to make a comparison based on the donor unit effe...
