In this study, synthesis and characterization of poly(dihalophenylene oxide)s were done by thermal decomposition of diamminebis(trichlorophenolato) copper(II) and diamminebis(tribromophenolato) Cu(II) complexes in solid state. 2,4,6-trichlorophenol (TCP), 2,4,6-tribromophenol (TBP) and ammonia were used as ligands in the complex syntheses. The complexes were characterized by means of X-ray diffraction, FTIR, DSC, mass spectroscopy, magnetic susceptibility and C, H, N elemental analyses. Synthesized complexes were decomposed thermally in solid state for the production of poly(dihalophenylene oxide)s. Polymerizations were carried out at two different conditions. In the first condition, the decomposition time was kept constant at 3 hours and temperature was varied for each sample to observe the effect of temperature on decomposition. In the second condition, the decomposition temperature was kept constant at maximum conversion temperature and the period of time was varied from 3 hours to 48 hours in order to define the effect of time on the decomposition. Synthesized polymers were characterized by FTIR, 1H-NMR, 13C-NMR, DSC, SEM, FAAS and viscometric measurements. At the end of the study, it was observed that, the percent conversion and the structure of the polymeric product depend on polymerization condition and the type of the starting complex.

Synthesis, characterization and electrochromic properties of conducting copolymers of terephthalic acid bis-(thiophen-3-ylmethyl)thioester with thiophene and pyrrole and conducting polymer of 1-(4-fluorophenyl)-2,5-di(thiophen-2-yl)-1h-pyrrole Türkarslan, Özlem; Toppare, Levent Kamil; Department of Chemistry (2006) Terephthalic acid bis-(thiophen-3-ylmethyl)thioester (TTMT) was synthesized via the reaction of thiophen-3-ylmethanethiol with terephthaloyl dichloride. Nuclear magnetic resonance (1H-NMR) and Fourier transform infrared (FTIR) spectroscopies were utilized for the characterization of the monomer. This 3-functionalized thiophene monomer was polymerized in the presence of thiophene (Th) and pyrrole (Py) upon constant potential application in acetonitrile/tetrabutylammonium tetrafluoroborate (TBAFB). The result...
Characterization of conducting polymers of ester linkage containing thiophene derivatives via mass spectroscopy Aslan, Evren; Toppare, Levent Kamil; Department of Chemistry (2004) In order to investigate the thermal and structural characteristics of terepthalic acid bis-(2-thiophen-3-yl-ethyl)ester (TATE), decanedioic acid bis-(2-thiophen-3-yl- ethyl) ester (DATE) and octanoic acid 2-thiophen-3-yl-ethyl ester (OTE), their corresponding homopolymers, copolymers with thiophene and polythiophene, pyrolysis mass spectrometry technique was utilized. The results were discussed in detail considering the effects of spacer group in between ester linkages. Thermal Gravimetry Analysis was used ...
Synthesis and characterization of a new soluble polythiophene derivative and its electrochromic application Tarkuç, Simge; Toppare, Levent Kamil; Department of Chemistry (2006) The Knorr-Paal reaction of 1,4-di(2-thienyl)-1,4-butanedione with aniline to yield 1-phenyl-2,5-di(2-thienyl)-1H-pyrrole (PTP) was performed in the presence of catalytical amounts of p-toluenesulfonic acid (PTSA). Chemical polymerization of the monomer yielded a soluble polymer. Structures of both the monomer and the polymer were investigated by Nuclear Magnetic Resonance (1H and 13C NMR) and Fourier Transform Infrared (FTIR) Spectroscopy. The average molecular weight of the chemically synthesized polymer w...
Covalent immobilization of glucose isomerase on poly(2-hydoxyethyl methacrylate) particles Yıldız, Ümit Hakan; Hasırcı, Nesrin; Department of Chemistry (2004) In this study, poly (2-hydroxyethyl methacrylate), P(HEMA), particles were prepared by suspension polymerization of the monomer 2-hydroxyethyl methacrylate with addition of ethylene glycol dimethyacrylate, EGDMA, as cross linker. Glucose isomerase, GI, enzyme was covalently immobilized on the prepared P(HEMA) particles after activation of the particles with cyanuric chloride. The activities of the free and immobilized enzymes were measured with Ethanol-Carbazole method. The immobilization of GI on P(HEMA) p...
Synthesis, characterization and electrical properties of diazophenylene and diazodiphenylene bridged co, ni, cu, ce, and er phthalocyanine polymers Alkan, Cemil; Alkan, Cemil; Department of Polymer Science and Technology (2004) In this research, diazophenylene and diazodiphenylene bridged metal-phthalocyanine polymers were produced from diazonium salt of diaminophenylene/bensidin and pre-synthesized tetraamino metal phthalocyanines. Tetraamino metal phthalocyanine complexes of Co, Ni, Cu, Ce, and Er were obtained by reducing tetranitro metal phthalocyanine complexes synthesized from 3-nitrophthalic anhydride, urea, metal salt, and ammonium molybdate catalyst. Complexes and polymers were characterized by Fourier Transform Infrared ...
