Poly 4-(biphenyl-4-yl)-4'-tert butylspiro[benzo[d]imidazole-2,1'-cyclohexane] (P1), Poly 4-(biphenyl-4-yl)2-dodecyl-2H-benzo[d][1,2,3]triazole (P2), Poly(4-(5-(biphenyl-4-yl)-4-hexylthiophen-2-yl)-2-dodecyl-7(4-hexylthiophen-2-yl)-2H-benzo[d][1,2,3]triazole (P3) were synthesized via Suzuki cross coupling polycondensation reaction. Polymers are thermally stable with decomposition temperatures above 300 C. Electrochemical and optical studies revealed that P2 and P3 exhibit reversible redox behavior with multichromic properties. Polymers showed highly fluorescent properties both in thin film and solution forms. Photoluminescence quantum efficiencies of P2 and P3 are 0.70 and 0.57 in chloroform respectively.

Benzotriazole and benzothiadiazole containing conjugated copolymers for organic solar cell applications
KARAKUS, Melike; APAYDIN, Dogukan Hazar; Yildiz, Dilber Esra; Toppare, Levent Kamil; Çırpan, Ali (Elsevier BV, 2012-03-09)
2-Dodecyl benzotriazole (BTz) and benzothiadiazole (BTd) containing copolymers poly(4-(2-dodecyl-2H-benzo[d][1,2,3]triazol-4-yl)benzo[c][1,2,5]thiadiazole (P1), poly(4-(5-(2-dodecyl-7-(thiophen-2yl)-2H-benzo[d][1,2,3]triazol-4-yl)thiophen-2-yl)benzo[c][1,2,5]thiadiazole (P2) and poly(4-(5-(2-dodecyl-7-(4-hexylthiophen-2-yl)-2H-benzo[d] [1,2,3]triazol-4-yl)-3-hexylthiophen-2-yl) benzo[c][1,2,5] thiadiazole (P3) were synthesized via Suzuki polycondensation. We report the application of conjugated copolymers i...
Synthesis, characterization and electrochromic properties of a near infrared active conducting polymer of 1,4-di(selenophen-2-yl)-benzene
Aydemir, Kadir; Tarkuc, Simge; Durmus, Asuman; Günbaş, Emrullah Görkem; Toppare, Levent Kamil (Elsevier BV, 2008-04-15)
A novel selenophene-based monomer, 1,4-di(selenophen-2-yl)-benzene (DSB), was synthesized via Stille coupling reaction of 1,4-dibromobenzene and tributyl(2-selenophenyl)stannane. Conducting polymer (PDSB) was prepared electrochemically in the presence of tetrabutylammonium hexafluorophosphate (TBAPF(6)) as the supporting electrolyte in dichloromethane (DCM). The resulting conducting polymer was characterized by Cyclic Voltammetry, Fourier Transform Infrared and Ultraviolet-visible spectroscopy. Spectroelect...
SYNTHESIS OF BLOCK COPOLYMERS VIA ANION-TO-RADICAL TRANSFORMATION
HAZER, B; CAKMAK, I; KUCUKYAVUZ, S; NUGAY, T (Elsevier BV, 1992-10-01)
Synthesis of (methyl methacrylate)-styrene block copolymers was carried out using anion-to-radical transformation. For this purpose, living polystyryl anion, prepared by using a new anionic difunctional initiator, 1,5-di(2-(3,3-dimethyl butyl-1-lithio)naphthalene, was terminated by the addition of 4,4'-bromomethyl dibenzoyl peroxide. Polystyrene samples having peroxide terminal groups were then used as initiators in the polymerization of methyl methacrylate. Block copolymers were characterized by spectrosco...
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...
LATTICE POLYMERS - BEHAVIOR FAR FROM THETA-CONDITIONS
YURTSEVER, E; ISSEVER, S (Elsevier BV, 1992-01-01)
Two-dimensional Monte-Carlo simulations of lattice polymers were carried out employing Lennard-Jones (LJ) type intramolecular interactions. The shape-dependent properties of these polymers were studied over a large range of interaction parameters and temperatures. The variation of the critical constant was also analysed. Two-dimensional surfaces of sections were used to determine the portions of the parameter space which corresponded to theta-conditions. The behaviour of LJ polymers far from theta-condition...
