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 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 ...
Synthesis of conducting polymers of terepthalic acid bis-(2-thiophen-3-yl-ethyl)ester and investigation of their electrochromic properties
Coşkun, Yelda; Toppare, Levent Kamil; Department of Chemistry (2004)
Terepthalic acid bis-(2-thiophen-3-yl-ethyl)ester (TATE) was synthesized through the reaction of 2-thiophen-3-yl-ethanol and terepthaloyl chloride. Electrochemical behavior of the TATE and TATE in the presence of thiophene were studied by cyclic voltammetry (CV). The chemical structure of monomer is characterized via Nuclear Magnetic Resonance Spectroscopy (NMR) and Fourier Transform Infrared Spectroscopy (FTIR). Homopolymer of TATE was synthesized by galvanostatic and potentiostatic methods, and copolymeri...
Synthesis of Fluorene-Type Thin Film Under Biphenyl/Methane Plasma Environment
Mansuroğlu, Doğan; Manolache, Sorin (2015-10-01)
Fluorene-type (C13H10) thin films were synthesized by using the mixture of biphenyl (C12H10) and methane (CH4) plasma. The reactor is a parallel plate installation; upper electrode is connected to 13.56MHz rf power and lower electrode is grounded. The thin films were deposited by applying a negative bias potential between the substrate and the wall of reactor. The films were investigated by residual gas analysis (RGA), UV-vis spectroscopy, atomic force microscope (AFM) and ellipsometry. They had significant...
