Design, synthesis, and electrochemical properties of two novel donor-acceptor-donor type benzimidazole and thiophene based monomers; 2-(4-fluorophenyl)-4,7-di(thiophen-2-yl)-1H-benzo[d]imidazole (BIPF) and 2-(3-fluorophenyl)-4,7-di(thiophen-2-yl)-1H-benzo[d]imidazole (BIMF) were highlighted. The position of fluorine as a substituent was varied from para- to meta- in order to investigate position effects on the electrochemical and optical properties of electrochemically synthesized polymers. Both polymers were p type dopable and they can be switched between orange and blue color during p-doping/dedoping. Significant improvements in the percent transmittance for PBIMF were observed compared to similar molecules in literature.

The effect of para-cyclophane structure on cyclacenes Türker, Burhan Lemi (2000-02-01) Semiempirical molecular orbital treatment at the level of AMI type has been performed on the Huckel type cyclacenes having the normal and the skew type para-cyclophane moiety embedded into their structures. The cyclophane effect is found to be operative on the lower members by veiling the cryptoannulenic effect which is influential on the heats of formation values and the frontier molecular orbital energies of the higher members as well as the parent cyclacenes.
INVESTIGATION OF DONOR, ACCEPTOR AND SUBSTITUENT EFFECT ON PHTHALIMIDE AND THIENO[3,4-c]PYRROLE-4,6-DIONE BASED DONOR-ACCEPTOR-DONOR TYPE MONOMERS AND POLYMERS Çakal, Deniz; Önal, Ahmet Muhtar; Cihaner, Atilla; Department of Chemistry (2021-11-26) Conjugated organic materials comprise a major field of material chemistry focused on the improvement of new building blocks for the synthesis of novel semiconducting materials with advanced functional properties. Such semiconducting systems have the advantage of low cost, solution processability and flexibility and find many applications in the field of plastic photovoltaics, electrochromics and display technologies. The electronic and optical features of these semiconducting organic materials can be tailor...
Studies towards synthesis of urea containing helical polymers Çalışgan, Gizem; Akdağ, Akın; Doğan, Özdemir; Department of Chemistry (2016) This thesis deals with design and synthesis of chiral polyurea type polymers. These polymers were analyzed with molecular mechanics that they could take a helical form. The polymers are polyurea type polymers and ureas are synthesized by treating isocyanates with amines. Starting from tartaric acid, ((4S,5S)-2,2-dimethyl-1,3- dioxolane-4,5diyl)dimethaneamine was synthesized. The other diamine was naturally occuring L-lysine. These diamine functionalized compounds were treated with pphenylene diisocyanate sy...
The Effect of Ultrasonication on the Size and Morphology of Iron Oxide - Chitosan Nano and Microparticles Akin, Deniz; YAKAR, ARZU; Gündüz, Ufuk (2013-04-28) The aim of this study is to synthesize magnetic Fe3O4-chitosan nano and microparticles (Fe3O4-CPs) by suspension cross-linking and ionic gelation methods and investigate the effect of ultrasonication on the size, morphology and magnetic properties. The synthesized particles were characterized by transmission electron microscopy (TEM), dynamic light scattering (DLS) and vibrating sample magnetometry (VSM). The results showed that the ultrasonication decreased the mean particle diameter and enhanced magnetic ...
The impact of [1,2,5]chalcogenazolo[3,4-f]-benzo[1,2,3]triazole structure on the optoelectronic properties of conjugated polymers Alkan, Ecem Aydan; GÖKER, SEZA; Sarigul, Hatice; Yıldırım, Erol; Udum, Yasemin Arslan; Toppare, Levent Kamil (2020-04-01) Two novel conjugated near-infrared (NIR) absorbing donor-acceptor type copolymers comprising benzodithiophene as the donor and [1,2,5]chalcogenazolo[3,4-f]-benzo[1,2,3]triazole derivatives as the acceptors, spaced with thiophene as the pi-bridge, were designed and synthesized via Stille polycondensation reaction. The effect of acceptor strength on optoelectronic properties was targeted and investigated. Branched alkyl chains (the extended 2-octyl-1-dodecyl alkyl chain; -C8C12) were introduced to 5H-[1,2,3]t...
