Synthesis and characterization of poly(oxalic acid dithiophen-3-yl methyl ester) and thiophene ended poly-caprolactone
Kerman, İpek; Toppare, Levent Kamil; Department of Chemistry (2004)
Synthesis and characterization of thiophene ended poly-e-caprolactone (PCL) and oxalic acid dithiophen-3-yl methyl ester (ODME) and their copolymers with both pyrrole and thiophene were achieved. Chemical structure of the precursor polymer and monomer were investigated Redox behavior of polymer and monomers were determined by Cyclic Voltammetry (CV). Structural characterization of samples were carried out by 1H, 13C Nuclear Magnetic Resonance (NMR) and Fourier Transform Infrared Spectroscopy (FTIR). Conduct...
Synthesis and electrochromic properties of conducting copolymers of dioxocino-and dithiocino- quinoxalines with bithiophene
Beyazyıldırım, Şenize; Toppare, Levent Kamil; Department of Chemistry (2005)
Two new monomers; 2-benzyl-5,12-dihydro-2Hpyrrolo[ 3̕,4̕:2,3][1,4]dioxocino[6,7-b]quinoxaline (DPOQ) and 5,12- dihydrothieno[3̕,4̕:2,3][1,4]dithiocino[6,7-b]quinoxaline (DTTQ), were synthesized. The chemical structures of the monomers were characterized by Nuclear Magnetic Resonance (1H-NMR), Fourier Transform Infrared (FTIR) and Mass Spectrometry (MS). Copolymer of DPOQ with bithiophene (BT) was synthesized via potentiostatic electrochemical polymerization in acetonitrile (ACN)-tetrabutylammonium tetrafluo...
Synthesis and characterization of electrochemically polymerized metal-free, nickel and zinc containing phthalocyanine derivatives
Yavuz, Arzu; Aras, Leyla; Department of Polymer Science and Technology (2009)
In the first part of this study, 4-(2,5-di-2-thiophen-2-yl-pyrrol-1-yl)-phthalonitrile (SNS-PN) was synthesized by utilizing 1,4-di(2-thienyl)-1,4- butadione (SOOS) and 4-aminophthalonitrile via Knorr-Paal Reaction. Nuclear magnetic resonance (1H NMR and 13C NMR) and fourier transform infrared (FTIR) spectroscopies were utilized for the characterization of this compound. SNS-PN monomer was then electrochemically polymerized in acetonitrile/0.2 M LiClO4 solvent/electrolyte couple. Characterizations of the re...
Synthesis and characterization of a polybenzoxazine from a difunctional amine and a trifunctional phenol
Kaya, Şafak; Tinçer, Teoman; Department of Polymer Science and Technology (2009)
Synthesis of a polymer with benzoxazine units in the main chain backbone by a trifunctional phenol, a difunctional amine, and paraformaldehyde was achieved. Thermal, mechanical and spectroscopic characterization and the viscosity properties of the synthesized polymer were studied. In the first step of this study, a fast and feasible method for the synthesis of the benzoxazine precursors was developed since some methods mentioned in the literature about the synthesis of the benzoxazine derivatives last long ...

Orhan Lekesiz, Tuğba; Hacaloğlu, Jale; Kayran, H. Ceyhan; Department of Chemistry (2014)
Polybenzoxazines possessing excellent mechanical and physical properties has been developed to overcome the shortcomings associated with the use of traditional phenolics. Various approaches for performance improvement of polybenzoxazine were examined. These approaches include alloying with other high performance polymers, hybridization with inorganics, and designing of novel monomers as well as high molecular weight polymeric precursors. In the first part of this work, benzoxazines based on phenol and anili...
