dc.description.abstractTicari kimyasal aminler olan Piridin-4-amin, Oktadekan-1-amin, 4-heksil anilin ve L-fenillalanin çıkış maddeleri ile ayrı ayrı 2 aşamalı sentez ile difenilamin türevleri elde edildi. Ardından elde edilen difenilamin türevleri 3,3',4,4'-Bifeniltetrakarboksilik dianhidrit ve piromellitik dianhidrit ile 4,4'-diamino-2,2'-stilbendisülfonik asit esaslı Poilimid 1 (PI1), Poilimid 2 (PI2), Poilimid 3 (PI3), Poilimid 4 (PI4) ve Poilimid 5 (PI5) sentezi gerçekleştirildi. PI1, PI2, PI3, PI4 ve PI5'in kuantum kimyasal hesaplamaları Gaussian 09W programı kullanılarak yoğunluk fonksiyonel teorisi (DFT) ve zamana bağlı yoğunluk fonksiyonel teorisi (TD-DFT) çalışmaları ile geometri optimizasyon, Muliken atomik yükler, dipol moment hesaplamaları, HOMO LUMO enerjilerinin hesaplamaları, MEP analiz ve NBO analiz incelendi. 1H-NMR, FT-IR, UV-görünür spektroskopik analizler ve DSC analizi ve TGA/DTA ısıl analizler ile sentezlenen bileşiklerin ve polimerlerin karakterizasyonları gerçekleştirildi.
dc.description.abstractDiphenylamine derivatives were obtained by separate 2-step synthesis with commercial chemical amines, Pyridine-4-amine, Octadecane-1-amine, 4-hexyl aniline and L-phenylalanine starting materials. Subsequently, the obtained diphenylamine derivatives 3,3',4,4'-Biphenyltetracarboxylic dianhydride and pyromellitic dianhydride and 4,4'-diamino-2,2'-stilbenedisulfonic acid based Polyimide 1 (PI1), Polyimide 2 (PI2), Polyimide 3 (PI3), Polyimide 4 (PI4) and Polyimide 5 (PI5) synthesis was carried out. Quantum chemical calculations of PI1, PI2, PI3, PI4 and PI5 using Gaussian 09W program, density functional theory (DFT) and time dependent density functional theory (TD-DFT) studies, geometry optimization, Muliken atomic charges, dipole moment calculations, HOMO LUMO Calculations of energies, MEP analysis and NBO analysis were examined. Characterizations of synthesized compounds and polymers were performed by 1H-NMR, FT-IR, UV-Visible spectroscopic analyzes and DSC analysis and TGA/DTA thermal analysis.en_US
