In this study, four novel silafluorene (SiF) and benzotriazole (Btz) bearing conjugated polymers are synthesized. In the context of electrochemical and optical studies, these polymers are promising materials both for electrochromic device (ECD) and polymer solar cell (PSC) applications. All of the polymers are ambipolar (both p- and n-dopable) and multichromic. Electrochemistry experiments indicate that incorporation of selenophene instead of thiophene unit increases the HOMO energy level of the polymers. Power conversion efficiency of the PSCs reached 1.75% for PTBTSiF, 1.55% for PSBSSiF, 2.57% for PBTBTSiF, and 1.82% for PBSBSSiF. The hole mobilities of the polymers are estimated through space charge limited current (SCLC) model. PBTBTSiF has the highest hole mobility as 2.44 x 10(-3) cm(2) V s(-1).

Fused structures in the polymer backbone to investigate the photovoltaic and electrochromic properties of donoracceptor-type conjugated polymers
CEVHER, ŞEVKİ CAN; UNLU, Naime Akbasoglu; OZELCAGLAYAN, Ali Can; APAYDIN, Dogukan Hazar; Udum, Yasemin Arslan; Toppare, Levent Kamil; Çırpan, Ali (Wiley, 2013-05-01)
In this study, two new benzotriazole (BTz) and dithienothiophene (DTT) containing conjugated polymers were synthesized. After successful characterizations of the monomers by proton-nuclear magnetic resonance (1H NMR) and carbon-NMR (13C NMR) techniques, poly(4-(dithieno[3, 2-b:2,3-d]thiophen-2-yl)-2-(2-octyldodecyl)-2H-benzo[d][1,2,3] triazole) P1 and poly(4-(5-(dithieno[3,2-b:2,3-d]thiophen-2-yl)thiophen-2-yl)-2-(2-octyldodecyl)-7-(thiophen-2-yl)-2H-benzo[d][1,2,3]triazole) P2 were synthesized via a typica...
Asymmetric syntheses of various novel chiral ligands with norbornene backbone : the use of chiral catalyst in asymmetric reactions
Elmalı, Olcay; Tanyeli, Cihangir; Department of Chemistry (2005)
The synthetic strategy of this study mainly depends upon the asymmetric desymmetrization of meso norbornene type an anhydride. Asymmetric desymmetrization was achieved by using chinchona alkaloids under kinetically controlled conditions. The resultant mono ester carboxylic acid was epimerized to trans configuration. Subsequent esterification followed by lithium aluminum hydride reduction afforded the first chiral diol ligand with 98 % ee. Transformation of diol to corresponding trans diamine was achieved vi...
Polymerization of 2-hydroxyethyl acrylate in bulk and solution by chemical initiator and by ATRP method
Vargun, E; Usanmaz, Ali (Wiley, 2005-09-01)
In this study, 2-hydroxyethyl acrylate (HEA) was polymerized to obtain polymers that can be used as hydrogel and copolymerized for biomedical applications. Bulk, solution, and atom transfer radical polymerization (ATRP) techniques at different temperatures were applied. The polymerization in bulk form was carried out in vacuum and in open atmosphere. The polymerization curves showed autoacceleration mechanism and the limiting conversion was 100%. The polymers obtained were insoluable in most common solvents...
Selenophene-bearing low-band-gap conjugated polymers: tuning optoelectronic properties via fluorene and carbazole as donor moieties
Yasa, Mustafa; GÖKER, SEZA; Toppare, Levent Kamil (Springer Science and Business Media LLC, 2020-05-01)
In this study, two donor-acceptor (D-A)-type conjugated polymers, namely PQSeCz and PQSeFl, were designed and synthesized. Selenophene was incorporated as the pi-bridge and quinoxaline as an acceptor unit, while carbazole and fluorene were used as the donor units. Polymers were synthesized via palladium-catalyzed Suzuki polymerization reaction. All molecules were characterized by H-1 and C-13 NMR spectroscopy. The weight and number average molecular weights of the two polymers were determined by gel permeat...
Asymmetric synthesis of N-aryl substituted chiral 1,4-aminoalcohol derivatives and applications in various asymmetric transformation reactions
Odabaş, Serhat; Tanyeli, Cihangir; Department of Chemistry (2007)
The asymmetric synthesis of N-aryl substituted chiral 1,4-aminoalcohols and their applications in asymmetric borane reduction and enantioselective diethylzinc addition to benzaldehyde reactions were performed starting from meso-anhydride 51 that is the cycloadduct of cyclopentadiene and maleic anhydride. The desymmetrization of meso-anhydride 51 was achieved by using quinine or quinidine with very high enantiomeric excess value (up to 98% ee) and with high chemical yield. The quinine-mediated desymmetrizati...
