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) reactions. In this thesis, triazene-substituted terminal and non-terminal alkyne substrates are used as electron-donors which react with strong electron-acceptors TCNE and TCNQ. Optoelectronic properties of obtained push-pull dyes are characterized via UV/Vis spectroscopy and theoretical calculations

Accuracy of the Surface Integral-equation Formulations for Large Negative Permittivity Values Karaosmanoglu, B.; Ergül, Özgür Salih (2017-05-25) Computational solutions of plasmonic problems involving metals at optical frequencies formulated with surface integral equations are considered. Numerical inaccuracies arise when using the conventional formulations for penetrable bodies, especially as the negative real permittivity becomes very large at the lower frequencies of the optical spectrum. In order to close the gap between plasmonic and perfectly conducting simulations, it is required to extend the applicability of surface integral equations to in...
Heterocycle-based push-pull NLOphores: investigation of linear and non-linear optical properties Karagöllü, Başak; Dengiz, Çağatay; Department of Chemistry (2022-12-19) Organic nonlinear optical materials are substantial in the technology era we live in, due to their applications in telecommunications, data storage, real-time target recognition, optoelectronics, and optical signal processing. The distinct intramolecular charge transfer (ICT) properties of conjugated push-pull chromophores provide high polarization and thus a strong NLO response can be obtained. NLOphores are designed to obtain more efficient and rapid NLO responses and [2+2] cycloaddition-retroelectrocycli...
Analysis of Lossy Dielectric Objects with the Multilevel Fast Multipole Algorithm Ergül, Özgür Salih (2011-07-08) Rigorous solutions of electromagnetics problems involving lossy dielectric objects are considered. Problems are formulated with two recently developed formulations, namely, the combined-tangential formulation (CTF) and the electric and magnetic current combined-field integral equation (JMCFIE), and solved iteratively using the multilevel fast multipole algorithm (MLFMA). Accuracy and efficiency of solutions are compared for different objects and conductivity values. We show that iterative solutions of CTF a...
Modified Superformula Contours Optimized via Genetic Algorithms for Exponentially Converging 2D Solutions of MFIE Guler, Sadri; Onol, Can; Ergül, Özgür Salih; Sever, Emrah; Dikmen, Fatih; Tuchkin, Yury A. (2017-05-25) An infinitely smooth parametrical representation with derivatives of all orders is used, resulting into exponentially converging solutions of magnetic field integral equation (MFIE) in 2D either for TM or TE polarized excitations. A version of superformula modified for this purpose has been subject to optimization of its parameters via genetic algorithms to provide smooth parameterization for a desired boundary in two-dimensional problems. The organization of the MFIE kernel and convergence of the solution ...
Performance of discrete dipole approximation for prediction of amplitude and phase of electromagnetic scattering by particles Ayranci, Isil; Vaillon, Rodolphe; Selçuk, Nevin (2007-01-01) Electromagnetic scattering provides useful signatures for nonintrusive particle characterization. Scattered wave which carries characteristic information about particles is identified completely by its intensity, polarization state and phase. Recent developments in measurement techniques have enabled measurement of phase of the scattered wave which is a source of additional information about particles. In the present study, accuracy of discrete dipole approximation (DDA) in predicting amplitude and phase of...
