Conjugated materials play an indispensable role in daily life due to their extraordinary properties and applications. Of particular interest are the donor–acceptor-type push–pull chromophores since they have already been utilized in many advanced applications such as organic light emitting diodes (OLEDs), organic field effect transistors (OFETs), dye-synthesized solar cells (DSSCs), and non-linear optical (NLO) devices. The thermal [2+2] cycloaddition reactions are chemical transformations that we will study in detail in this thesis to access triazene-substituted homoconjugated push–pull chromophores. Moreover, the formal [2+2] cycloaddition-retroelectrocyclization transformations were utilized for the preparation of the indole-substituted push–pull systems. The optoelectronic properties of the chromophores will be explored by UV/Vis spectroscopy and computational analysis.

DESIGN AND SYNTHESIS OF TRIAZENE-SUBSTITUTED PUSH-PULL DYES USING FORMAL [2+2] CYCLOADDITION RETROELECTROCYCLIZATION REACTIONS Mammadova, Flora; Dengiz, Çağatay; Department of Chemistry (2022-1-26) Conjugated push-pull chromophores are valuable due to intramolecular electron charge transfer band (ICT), second and third order nonlinear optical properties. These extraordinary features allow to use them in the area of optoelectronics where advanced applications are possible. Organic light emitting diodes (OLEDs), solar cells, organic field effect transistors (OFETs) are some examples. Synthesis of push pull chromophores is possible by click-type [2+2] cycloaddition retroelectrocyclization (CA-RE) reactio...
Modeling of Spherulite Microstructures in Semicrystalline Polymers Oktay, Hasan Emre; Gürses, Ercan (2014-09-04) Polymers constitute an important class of materials with a wide range of application areas in modern life. Among these, semicrystalline polymers (SCP), such as high-density polyethylene (HDPE), Nylon-6, poly(ethylene terephthalate) (PET), isotactic polypropylene (iPP) and ultra high molecular weight polyethylene (UHMWPE), form a sub-set with a significant technological interest. Owing to remarkable deformability and toughness, good impact strength, very low gas-permeability, superior wear resistance and bio...
STUDIES ON CHIROPTICAL PROPERTIES OF 2-CARBOXY-5,6-BENZOCOUMARIN: EFFECT OF SIDE CHAIN Öztürk, Perihan; Akdağ, Akın; Department of Chemistry (2022-10-21) The synthesis and examination of chiroptical materials are essential for their considerable potential in diverse applications. With that, induced chirality is a particular condition for the design of chiroptical compounds where the chiral information of a chiral compound is transferred to a UV-Vis reporter. This approach allows the utilization of numerous chiral compounds for chiroptical studies. Accordingly, in this study, the use of 2-carboxy-5,6-benzocoumarin (3-oxo-3H- benzo[f]chromene-2-carboxylic acid...
Synthesis, aqueous solution behavior and layer-bylayer self-assembly of poly(2-alkyl-2-oxazoline)s Çağlı, Eda; Erel Göktepe, İrem; Department of Chemistry (2019) Poly(2-alkyl-2-oxazoline)s (PAOXs), are of interest for biomedical applications due to their important biological properties such as nontoxicity and biocompatibility. PAOXs with short-alkyl chains exhibit temperature-responsive behaviour which is advantageous for various biomedical applications. This dissertation focused on synthesis, aqueous solution behaviour, post-functionalization and layer-by-layer (LbL) self-assembly of PAOXs. In addition, it aimed to examine the surface properties of PAOX LbL films a...
Stability, thermophysical properties and performance assessment of alumina-water nanofluid with emphasis on ultrasonication and storage period Mahbubul, I. M.; Elcioglu, E. B.; Amalina, M. A.; Saidur, R. (Elsevier BV, 2019-03-01) Owing to the improvements in thermophysical properties, nanofluids are considered advantageous over pure fluids in heat transfer applications. However, these improvements may be regarded as meaningful for applications provided that optimum dispersion of nanoparticles is ensured throughout the process, which mostly depend on preparation technique. In this study, alumina (Al2O3)-water nanofluids of 0.5 vol% were prepared using ultrasonication (up to 5 h) and stored at stationary condition until 30 days. We ha...
