Polymerization and characterization of various di(pyridine)bis(trihalophenolato)cobalt(II) complexes in solid and melt states

The syntheses of distorted tetrahedral bis(pyridine)bis(trihalophenolato)cobalt(II) complexes from an aqueus solution were achieved and their characterization by FT-IR, X-ray, DSC, UV-visible and elemental analysis in solid state or in melt form is reported. Polymerizations of these complexes were accomplished either at constant temperature, employing different time intervals or constant decomposition times while varying the temperature range. The slow decomposition at constant temperature leads to long chain products, whereas long chains formed at higher temperatures were during a constant time. The resulting poly(dihalophenylene oxide)s were characterized by FT-IR, H-1 NMR, C-13 NMR spectral analysis, differential scanning calorimetry and molecular weight determinations by viscometric method.

BASTURKMEN, M; ISCI, H; KISAKUREK, D (Wiley, 1993-01-01)
Synthesis of four-coordinated (tetrahedral) trichlorophenol cobalt(II) complex with neutral ligand pyridine was achieved from the aqueous solution and its characterization was performed by UV-visible, IR spectral and CHN analysis. Solid state thermal polymerization of the complex was accomplished first at constant temperature employing different time intervals and secondly at constant decomposition time. The poly(dichlorophenylene oxide)s so synthesized were characterized by IR, H-1 NMR and C-13 NMR spectra...
Synthesis and surface properties of polydimethylsiloxane-based block copolymers: poly[dimethylsiloxane-block- (ethyl methacrylate)] and poly[dimethylsiloxane-block-(hydroxyethyl methacrylate)]
Vargun, Elif; Usanmaz, Ali (Wiley, 2010-12-01)
A polydimethylsiloxane (PDMS) macroazoinitiator was synthesized from bis(hydroxyalkyl)-terminated PDMS and 4,4'-azobis-4- cyanopentanoic acid by a condensation reaction. The bifunctional macroinitiator was used for the block copolymerization of ethyl methacrylate (EMA) and 2-(trimethylsilyloxy) ethyl methacrylate (TMSHEMA) monomers. The poly(DMS-block-EMA) and poly(DMS-block-TMSHEMA) copolymers thus obtained were characterized using Fourier transform infrared and (1)H NMR spectroscopy and differential scann...

Sahin, E; Camurlu, P; Toppare, Levent Kamil; Mercore, VM; Cianga, I; Yagci, Y (Wiley, 2005-12-01)
Thiophene functionalized polystyrene samples (TFPS) were synthesized by atom transfer radical polymerization (ATRP) of styrene, followed by Suzuki coupling with 3-thiophene (Th) boronic acid. Conducting graft polymer of TFPS with thiophene was achieved at 1.5 V in tetrabutylammonium tetrafluoroborate/dichloromethane (TBAFB/DM) by electrochemical methods. Spectroelectrochemical analysis of the resulting copolymers [P(TFPS-co-Th)] reflected electronic transitions at 449, 721 and 880 nm, revealing pi - pi* tra...
Photo- and electroluminescent properties of a π-conjugated copolymer containing 2,2′-bipyridyl units
Deichmann, Vitor Angelo Fonseca; Çırpan, Ali; KARASZ, Frank E.; AKCELRUD, Leni (Wiley, 2007-02-01)
The synthesis, structural characteristics, and photo- and electroluminescent properties of a soluble light-emitting copolymer built up of regularly alternating segments of 1,4-dihexyloxybenzene and 2,2'-bipyridyl (PBPyDHB) are described and discussed. Optical properties of the polymer were investigated in solution and solid-state conditions, demonstrating that in film form the predominant emission centers are inter-macromolecular aggregates, either in photo- or electroluminescence. Thermogravimetric analysi...
Template-free microsphere and hollow sphere formation of polymethylanilines
Icli, Merve; Önal, Ahmet Muhtar; CİHANER, ATİLLA (Wiley, 2009-06-01)
BACKGROUND: Microsphere and/or hollow sphere formation of methyl-substituted polyaniline derivatives was investigated via chemical polymerization where different sets of conditions were examined. It was found that a variety of parameters (e.g. types and concentrations of monomer and oxidant, polymerization time, solvent with and without acid) have a crucial influence on the morphology of the resulting polyaniline derivatives.
