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 synthesized from p-phenylene diamine and triphosgene and polymerized with diamines. Similarly, (S)-methyl 2,6-diisocyanatohexanoate was synthesized by reacting with triphosgene and L-lysine methyl ester and polymerized with L-lysine. The results toward synthesis of these 'helical' polymers were discussed.

Development of new methods for the synthesis of pyrazoles, 4-iodopyrazoles, isoxazoles and 1,2,4-oxadiazoles Kıvrak, Arif; Zora, Metin; Department of Chemistry (2011) Synthesis of five-membered heteroaromatic compounds such as pyrazoles, isoxazoles and 1,2,4-oxadiazoles are important for pharmaceutical industry and material science due to their applications. Although there are many methods to prepare such compounds, new variants continue to appear since they exhibit a wide range of biological and medicinal activities. In this thesis, new methods were developed for the synthesis of 4-iodopyrazoles, pyrazoles, isoxazoles, 1,2,4-oxadiazoles and/or 1,2,4-oxadiazepines. In th...
Investigation of optoelectronic properties of benzotriazole and thiazole bearing conjugated polymers Ünay, Hakan; Çırpan, Ali; Department of Polymer Science and Technology (2019) This thesis deals with the design, synthesis and characterization of conjugated polymers P1 and P2 that have potential application in organic solar cell. Polymer design was accomplished by using band gap engineering method. According to that, benzodithiophene (BDT) and silafluorene were chosen as donor groups in P1 and P2 respectively. The acceptor parts were the same for both polymers including benzotriazole (BTZ) and thiazole group. According to electrochemical studies both polymers were having n-dopable ...
Novel studies on the chemoenzymatic synthesis of polychlorinated bicyclic systems and the synthesis of C2 and C3 symmetric chiral ligands Türkmen, Yunus Emre; Tanyeli, Cihangir; Department of Chemistry (2006) Optically active polychlorinated bicyclic systems are important starting materials for the synthesis of complex target molecules. In the first part of the study, the syntheses of several racemic and meso hexachloronorbornene derivatives were executed successfully, starting from hexachlorocyclopentadiene. The enantio-enriched acetoxymethyl derivative (-)-2 and the hemiester (-)-6 were synthesized in high e.e. values by using several hydrolase type enzymes. The absolute configuration of (-)-2 was determined b...
Development of acyl anion precursors and their applications Reis, Ömer; Demir, Ayhan Sıtkı; Department of Chemistry (2005) This thesis presents the development of new acyl anion precursors and their applications. The main concern of this thesis was to make use of acyl anion precursors in catalytic bond forming reactions. Toward this aim, previously known cyanide ion catalyzed cleavage of benzils was investigated in scope and efficiency in unsymmetrical benzoin condensation. Although benzils were proved to be useful entities as acyl anion precursors in benzoin condensation, they suffer some major drawbacks. Therefore acylphospho...
Comparison of Natural Halloysite With Synthetic Carbon Nanotubes in Poly(lactic acid) Based Composites Erpek, Canan Esma Yeniova; ÖZKOÇ, GÜRALP; Yılmazer, Ülkü (Wiley, 2017-11-01) The objective of this study is to compare the mechanical properties, structure and degradability of the nanocomposites prepared with tubular nanofillers, halloysite (HNT) and carbon nanotube (CNT) in poly(lactic acid) (PLA), and thermoplastic polyurethane (TPU) toughened PLA (T-PLA) matrices. In the PLA matrix, CNT increased, whereas HNT decreased the tensile strength with increasing filler content. Also, the elongation at break and impact strength decreased with increasing CNT content, but these properties...
