Organik Fotoiletkenlerin Yük Oluşum ve Saçılım Mekanizmalarının THz Spektroskopi ile İncelenmesi
Esentürk, Okan(2015-12-31)
Birçok uygulama alanında (elektronik, plazmonik, optik/kızıl ötesi cihazlarda) gelecek vaat eden organik yarıiletkenler, yüksek taşıyıcı hareketliliği, optik geçirgenliği ve yüksek mekanik ve kimyasal stabilitesi ile fotovoltaik cihazlarda kullanılma potansiyeli gerçekten dikkat çekicidir. Son yıllarda özellikle organik güneş enerji hücreleri yenilenebilir enerji ihtiyacını karşılamaya yönelik ekonomik bir çözüm olması nedeniyle araştırma alanında yoğun ilgi görmektedir. Geniş ve eğimli alanlara uygulana bi...
Controlled synthesis of organic-inorganic composite particles
Erçelik, Elif; Büküşoğlu, Emre; Aydoğan, Nihal; Department of Chemical Engineering (2022-8-26)
Liquid crystal (LC) is a state of matter having long-range orientational order between crystalline solid and isotropic liquid, and its molecular orientation can be altered with external stimuli. The polymerization of liquid crystal droplets has been widely used for the synthesis of LC-templated functional materials due to its ordering property and fluidic behavior. In this study, we investigated the synthesis of composite particles with controlled internal and interfacial structure using surface-modified na...
Syntheses of conjugated polymers and investigation the effect of gold nanoparticle - thiol interaction for organic solar cell application
Gülmez, Selin; Çırpan, Ali; Department of Chemistry (2022-8-31)
In this thesis, five benzo[c][1,2,5] thiadiazole-based conjugated polymers were synthesized. Four of them were synthesized via Stille and Suzuki coupling reactions and the remaining one was synthesized by post-polymerization. The effect of functional groups of the tip of the alkyl chain was analyzed. Moreover, thiol group and gold nanoparticle interaction on the organic solar cell efficiency for P1-SH were investigated. Electronic and optical band gaps of polymers were found as 1.85/1.81, 1.95/1.85, 1.83/1....
Synthesis and luminescence properties of tetraphenylethene-based small molecules used in organic light emitting diodes
Odabaş, Serhat; Tanyeli, Cihangir; Department of Chemistry (2014)
Organic light emitting diodes (OLED) is an exciting new technology that attracted much attention to scientist for emissive technology. The basic OLED structure consists of a stack of fluorescent organic layers sandwiched between a transparent conducting anode and metallic cathode. The important problems in luminescence is that, molecules aggregate in solid state that leads formation of excimers which results in emission quenching so that most of the luminescent materials show weak emissions in their solid f...
Syntheses of functional materials for organic photovoltaic and electrochromic device applications
Varlıoğlu, Figen; Günbaş, Emrullah Görkem; Department of Polymer Science and Technology (2017)
Thienothiophene based moities are widely investigated for organic solar cell applications. In this study, after synthesizing 2-ethylhexyl 4,6-dibromothieno [3,4-b]thiophene-2-carboxylate successfully, copolymerization with commercially available donor 4-(2-ethylhexyl)-2,6-bis(trimethylstannyl)-4H-dithieno[3,2-b:2',3'-d]pyrrole, DTPy, was performed via Stille coupling. At each step, Nuclear Magnetic Resonance (NMR) Spectroscopy were performed for structural analysis. Cyclic voltammogram was used for investig...
