Azo-containing compounds have recently been studied intensively due to their photoisomerization properties. Azo-containing compounds can be used in a wide variety of fields; e.g. pharmaceuticals, the paint industry, and molecular rotors. Use of such compounds for molecular rotors stems from its easy photoisomerization. These compounds are converted from trans to cis by irradiation. In addition, cis configurations of azo-containing compounds are inherently chiral properties due to their helical structure. In this thesis, new polymers and small compounds were synthesized and their photoisomerizations with/without polarized light were investigated. The photoisomerization studies of azobenzene in the presence of a chiral amine was expected to induce chirality on cis form, yet it did not. Moreover, chirality induction could be done with circulary and eliptically polarized light. Such investigations were also carried out. Although it was found that no chiral induction to cis form, it was postulated that this is due to the poor chiroptical properties of the trans/cis azobenzene unit.

Synthesis of Functionalized Novel alpha-Amino-beta-alkoxyphosphonates through Regioselective Ring Opening of Aziridine-2-phosphonates Polat-Cakir, Sidika; Beksultanova, Nurzhan; Doğan, Özdemir (Wiley, 2019-11-01) Aziridines are highly useful compounds as building blocks for the synthesis of important organic compounds. Amino acid synthesis by aziridine ring opening reaction is a good example to the use of aziridines. Although this reaction is studied by many groups, the synthesis of amino phosphonic acids is less explored. In this study, we have carried out the ring opening reaction of aziridinyl phosphonates with a variety of alcohols including the more functional propargylic and allylic alcohols. These reactions p...
SYNTHESIS OF 2,3-DITHIOFENIL DERIVATIVES OF PYRROL ON THE BASIS OF 2,2 '-THIONINE Maharramov, A. M.; Akay, P.; Akhmedov, I. M.; Safarova, A. S.; Qurbanova, M. M.; Huseynov, E. Z.; Musayeva, S. A. (2019-01-01) It is known that pyrrole and its derivatives are a part of many important natural compounds. Polymeric semiconductors also were obtained on the basis of 2,5-dithienyl-pyrrole electropolymerization and its derivatives. The work deals with the synthesis of 2,3-dithiophenyl-1H-pyrroles by the reaction of 2,2'-thionine with various enamines.
Synthesis of 1,2,3,5-tetrasubstituted pyrrole derivatives from 2-(2-bromoallyl)-1,3-dicarbonyl compounds Demir, Ayhan Sıtkı; Akhmedov, IM; Sesenoglu, O (Elsevier BV, 2002-12-02) 2-(2-Bromoallyl)-1,3-dicarbonyl compounds are converted into beta-enamino, beta-hydrazino esters and ketones, followed by base-promoted cyclization, leading to the formation of the corresponding 1,2,3,5-tetrasubstituted pyrroles. 1,2,4- and 1,2,3,4-Substituted pyrroles are also isolated as minor products. Starting from the 2-(2-bromoallyl)-cyclohexane-1,3-dione the corresponding tetrahydro indolone is prepared in good yield.
Synthesis of azobenzene containing macrocycles Hoşgör, Ege; Akdağ, Akın; Department of Chemistry (2021-2-10) Aromatic azo compounds are one of the well-known research topics of recent times due to their photoisomeric properties under ultraviolet or visible light. Generally, these substances undergo isomerization from the thermodynamically more stable trans isomer to the cis isomer when irradiated with appropriate light radiation. The incorporation of azo groups to the macrocycle skeleton is an important part of the supramolecular chemistry. Azobenzene photoisomerization is the key mechanism of molecular motors tha...
Synthesis of alpha-Fe2O3/TiO2 heterogeneous composites by the sol-gel process and their photocatalytic activity Bouziani, Asmae; PARK, JONGEE; Öztürk, Abdullah (Elsevier BV, 2020-09-01) alpha-Fe2O3/TiO2 heterogeneous composites were synthesized by the sol-gel process to increase the photocatalytic activity of TiO2. The structural, morphological, and optical characteristics of the composites were determined by X-ray diffraction, scanning electron microscope, and UV-vis diffuse reflectance spectroscopy. Results revealed that the incorporation of alpha-Fe2O3 to TiO2 widened the visible light absorption ability of TiO2. It was realized that the calcination temperature plays a crucial role in m...
