A series of benzotriazole (BTz)- and dithienopyrrole (DTP)-based three polymers; poly[2-(2-dodecyl-2H-benzo[d][1,2,3]triazol-4-yl)-4-hexyl-4H-dithieno[3,2-b:2',3'-d]pyrrole] (P1), poly[2- (5-(2-dodecyl-7-(thiophen-2-yl)-2H-benzo[d][1,2,3]triazol-4-yl)thiophen-2-yl)-4-hexyl-4H-dithieno[3,2-b:2',3'-d]pyrrole] (P2), and poly[2-(5-(2-dodecyl-7-(4-hexylthiophen-2-yl)-2H-benzo[d][1,2,3]triazol-4-yl)-3-hexylthiophen-2-yl)-4-hexyl-4H-dithieno[3,2-b:2',3'-d]pyrrole] (P3) was synthesized via Stille coupling. To investigate the effect of the p-bridges on the electrochromic properties of BTz-based polymers, thiophene and 3- hexylthiophene was incorporated between BTz and DTP moiety. Different p-bridges affected the HOMO and LUMO energy levels, coloration efficiency, switching time, and optical contrast.

Incorporation of Different Conjugated Linkers into Low Band Gap Polymers Based on 5,6-Bis(octyloxy)-2,1,3 benzooxadiazole for Tuning Optoelectronic Properties Goker, SEZA; HIZALAN, Gonul; KUTKAN, Seda; Udum, Yasemin Arslan; Çırpan, Ali; Toppare, Levent Kamil (2016-08-15) Four new 2,1,3-benzooxadiazole-based donoracceptor conjugated polymers, namely poly{9-(9-heptadecanyl)-9H-carbazole-alt-5,6-bis(octyloxy)-4,7-di(selenophen-2-yl)benzo[ c][1,2,5] oxadiazole)}(PSBSC), poly{9-(9-heptadecanyl)-9H-carbazole- alt-5,6-bis(octyloxy)-4,7-di(furan-2-yl) benzo[c][1,2,5]oxadiazole)}(PFBFC), poly{9,9-dioctyl-9H-fluorene-alt-5,6bis( octyloxy)-4,7-di(selenophen-2-yl) benzo[c][1,2,5] oxadiazole)} (PSBSFL), and poly{9,9-dioctyl-9H-fluorene-alt-5,6-bis(octyloxy)- 4,7-di(furan-2-yl) benzo[c][...
Effect of LiClO4 Salt on Dielectric Properties of Acrylonitrile-Methyl Methacrylate and Acrylonitrile-Isobutyl Methacrylate Copolymers VARGÜN, ELİF; ABACI, UFUK; SANKIR, MEHMET; Usanmaz, Ali; GÜNEY, HASAN YÜKSEL (2014-01-01) Poly(acrylonitrile-co-isobutyl methacrylate), PAN-co-PIBMA, and poly(acrylonitrile-co-methyl methacrylate), PAN-co-MMA copolymers are synthesized by emulsion polymerization. The structural characterization is done by FTIR and H-1-NMR spectroscopy and thermal analyses are performed by thermogravimetric analysis (TGA). After various amounts of LiClO4 salt loading into copolymer films, the dielectric properties of these films at different temperatures and frequencies are determined. The effects of different me...
Effect of the donor units on the properties of fluorinated acceptor based systems Önal, Ahmet Muhtar; Akdağ, Akın; Çakal, Deniz (Elsevier BV, 2020-10-01) A new series of monomers in the donor-acceptor-donor array, namely 5-fluoro-4,7-di(furan-2-yl)benzo[c][1,2,5]thiadiazole (F2BT-F), and 5-fluoro-4,7-di(selenophen-2-yl)benzo[c][1,2,5] thiadiazole (S2BT-F), bearing 5-fluorobenzo[c][1,2,5]-thiadiazole as the acceptor moiety and furan and selenophene as the electron donating groups was synthesized and polymerized electrochemically. To compare heteroatom effect, thiophene analogue of newly synthesized F2BT-F and S2BT-F namely, (5-fluoro-4,7-di(thiophen-2-yl)benz...
Influence of TiO2 Content on the Photocatalytic Activity of TiO2 B2O3 Glasses Prepared by the Sol gel Process Akkuş, Sıtkı Can; Kalem, Volkan; Park, Jongee; Öztürk, Abdullah (2016-12-01) A series of binary (1-x)TiO2 xB2O3 glasses with TiO2 content up to 80 mol% were prepared by the sol-gel technique using titanium tetraisopropoxide (C12H28O4Ti) and boric acid (H3BO3) precursors. Effects of initial precursor amount, and calcination temperature and time on the formation and photocatalytic properties of the glasses were investigated. The optimum amount of TiO2 was researched to get a glass possessing self-cleaning ability. The photocatalytic performance of the glasses was evaluated by the deco...
Effect of high-temperature on the swellable organically-modified silica (SOMS) and its application to gas-phase hydrodechlorination of trichloroethylene Sohn, Hyuntae; Çelik, Gökhan; Gunduz, Seval; Majumdar, Sreshtha Sinha; Dean, Stacey L.; Edmiston, Paul L.; Ozkan, Umit S. (2017-01-01) Pd catalysts supported on swellable organically-modified silica (SOMS) and high-temperature treated swellable organically-modified silica (H-SOMS) were characterized and tested for gas-phase hydrodechlorination (HDC) of trichloroethylene (TCE) conditions. The high-temperature treatment on SOMS resulted in an increase in surface area and pore diameter as well as significant improvement of Pd dispersion on H-SOMS with smaller Pd particle sizes compared to the Pd/SOMS catalyst. Although the high-temperature tr...
