Çelebi, Selin; Toppare, Levent Kamil; Department of Chemistry (2009)
A new neutral state green polymer, poly (2,3-bis(4-tert-butylphenyl)-5,8-di(1H-pyrrol-2-yl) quinoxaline) (PTBPPQ) was synthesized and its copolymer with bis(3,4-ethylenedioxythiophene) (BiEDOT) and 4,7-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-2-dodecyl-2H-benzo [1,2,3] triazole (BEBT) were produced. Finally polymers’ potential use as an electrochromic material was investigated. Electrochromic properties of the polymers were investigated by several methods including spectroelectrochemistry, kinetic and ...

Novel benzodithiophene type copolymer was synthesized through a solvent evaporation technique. Poly(5-(5-(4, 8-bis((2-ethylhexyl)oxy)benzo[1,2-b:4, 5-b']dithiophen-2-yl)thiophen-2-yl)-2, 3-bis(3, 4-bis(decyloxy)phenyl)-8-(thiophen-2-yl) quinoxaline) (P-TQTBDT) solar cells were encapsulated with conventional and Atomic Layer Deposition (ALD) techniques. Characterizations of the samples were carried out via nuclear magnetic resonance (NMR), gel permeation chromotagraphy (GPC) and cyclic voltammetry (CV) techn...
Novel donor-acceptor type polymers towards excellent neutral state green polymeric materials for realization of RGB based electrochromic device applications
Günbaş, Görkem Emrullah; Toppare, Levent Kamil; Department of Chemistry (2007)
Polymers having one of the three complementary colors (red, green, and blue) in the reduced state and high transmissivity in the oxidized state are key materials towards use in electrochromic devices and displays. Although many neutral state red and blue polymers were reported up to date, neutral state green polymeric materials appear to be limited. For potential application of electrochromic materials in display technologies, one should have to create the entire color spectrum and this can be only achieved...
Novel structured gadolinium doped ceria based electrolytes for intermediate temperature solid oxide fuel cells
Timurkutluk, Bora; Timurkutluk, Cigdem; MAT, MAHMUT DURSUN; Kaplan, Yuksel (Elsevier BV, 2011-11-15)
Novel three-layered intermediate temperature solid oxide fuel cell (SOFC) electrolytes based on gadolinium doped ceria (GDC) are developed to suppress the electronic conductivity of GDC, to improve the mechanical properties of the cell and to minimize power loss due to mixed conductive nature of GDC. Three different electrolytes are fabricated by sandwiching thin YSZ. ScSZ and ScCeSZ between two relatively thick GDC layers. An electrolyte composed of pure GDC is also manufactured for comparison. NiO/GDC and...
Novel phenanthrocarbazole containing conjugated polymers as high performance electrochromic materials
Atakan, Gizem; Günbaş, Emrullah Görkem; Department of Chemistry (2016)
For potential application of electrochromic materials in display technologies, materials having additive or subtractive primary colors in their neutral states that switch to a highly tranmissive states are desired since the entire color spectrum can be created using these materials. The RGB color model requires three complementary colors; red, green and blue. Even though the RGB colored polymers in the electrochromic research area were fulfilled over the past decade, towards high quality display application...
