Tosun, Ayşegül; Tanyeli, Cihangir; Department of Chemistry (2002)
ree nitroxyl radicals are popular in alcohol oxidation reactions as catalysts. The most useful ones are TEMPO (2,2,6,6-tetramethylpiperidinoxyl) derivatives. In this thesis, TEMPO based polymeric catalyst systems were synthesized. The most important property of these catalysts are being homogeneous and recyclable systems. In the synthetic strategy, the monomer systems which are needed for polymerization were synthesized from easily available norbornene derivatives via Mukaiyama and DCC coupling reactions. T...
Synthesis and characterization of water-soluble oligosalicylaldehyde-sulfanilic acid and its Cu(II), Co(II), Pb(II) complexes

This work presents the synthesis and characterization of a new water-soluble oligophenol derivative, 4-(2-hydroxybenzylideneamino)benzenesulfanic acid (OSAL-SA) and its metal complexes. The chemical structure of the water-soluble polymer was characterized by nuclear magnetic resonance (H-1 NMR) and Fourier transform infrared (FTIR) spectroscopies and thermogravimetric analyses (TGAs). Pb(II), Cu(II), Co(II) complexes of the polymer were also synthesized in methanol. Characterizations of water insoluble poly...
Synthesis of heterocyclic unit substituted carbazole derivatives and their electrochemical polymerization
Oğuztürk, Hatice Esra; Önal, Ahmet Muhtar; Tirkeş, Seha; Department of Polymer Science and Technology (2013)
The study comprises synthesis of 3,6 and 2,7 substituted carbazole derivatives. Substitution was done by furan groups. The main purpose to conduct this study is to synthesize new low band gap donor-acceptor type monomers and analyze the differences stem from the substitution site difference and alkyl chain effect attached to the nitrogen atom. For this aim, four monomers; 3,6-Di(2-furyl)-9H-carbazole (3,6-F-Cz-F), 3,6-Di(2-furyl)-9-ethyl-carbazole (3,6-F-N-et-F), 2,7-Di(2-furyl)-9-H-carbazole (2,7-F-Cz-F) ,...
Synthesis of conducting block copolymers and their use in the immobilization of invertase and polyphenol oxidase enzyme
Kıralp, Senem; Kıralp, Senem; Department of Chemistry (2004)
A new thiophene derivative containing menthyl group (MM) was synthesized and polymerized via chemical and electrochemical methods. Polymers obtained and MM itself were used to synthesize copolymers with pyrrole under conditions of constant potential electrolysis. Cyclic Voltammetry, thermal analysis and scanning electron microscopy analyses were performed for the characterization of samples. Immobilization of invertase and polyphenol oxidase enzymes was performed in the matrices obtained via copolymerizatio...
Studies towards green oxidation of alcohols with visible light
Akkaş, Kıvanç; Akdağ, Akın; Department of Chemistry (2014)
Conversion of alcohols to the corresponding carbonyl compounds is one of the key reactions in organic chemistry. For this, numerous methods have been developed. However, most of these methods produce environmentally hazardous waste. With this in mind, an environmentally benign method was attempted to be developed. The idea was borrowed from Dye Sensitized Solar Cells (DSSC); electron relay mechanism in DSSC to be replaced with oxidation of alcohols. First, TiO2 as metal oxide and O2 as electron acceptor wer...
