The synthesis of block and graft copolymers containing insulating and conducting polypyrrole or polythiophene segments via a two-step procedure is described. Synthetic pathways to prepare pyrrole and thiophene functional macromonomers involving conventional and controlled/living polymerizations such as anionic and cationic ring opening, atom transfer radical polymerization are discussed. The use of these macromonomers in subsequent electrochemical and chemical polymerizations, leading to the formation of copolymers, is presented. (C) 2003 Society of Chemical Industry.

Electrochemical polymerization and characterization of polyether-substituted aniline derivatives
Tirkeş, Süha; Oenal, Ahmet M. (Wiley, 2007-08-01)
New compounds consisting of aniline units linked by polyether bridges have been synthesized and their electrochemical polymerization was performed via constant potential electrolysis and cyclic voltammetry in an aqueous solution containing 3.0 moI L-1 H2SO4. Chemical polymerization was carried out using (NH4)(2)S2O8 as oxidizing agent. It was found that both methods gave the same polymer product without any cleavage of the polyether bridge between aniline rings. The polymers were characterized using the Fou...
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.
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...
Electrochemical synthesis of crowned conducting polymers : nature of radical cations in polymerization and mechanism of conductivity
Cihaner, Atilla; Önal, Ahmet Muhtar; Department of Chemistry (2004)
Poly(dibenzo-18-crown-6) (Poly(DB18C6)) was synthesized by electrochemical oxidation of dibenzo-18-crown-6 (DB18C6) using a mixture of acetonitrile and dichloromethane as solvent and tetrabutylammonium tetrafluoroborate (TBABF4) or tetrabutylammonium hexafluorophosphate (TBAPF6) as supporting electrolyte. The anodic polymerization of DB18C6 was investigated using in-situ ESR and in-situ UV-VIS spectroscopic techniques. Spectroelectrochemical (SPEL) properties and thermal analysis of the resulting polymers h...
Electrochromic properties of 'Trimeric' thiophene-pyrrole-thiophene derivative grown from electrodeposited 6-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)hexan-1-amine and its copolymer
Tarkuc, Simge; Ak, Metin; Onurhan, Erdal; Toppare, Levent Kamil (Informa UK Limited, 2008-01-01)
A centrosymmetric polymer precursor, namely 6-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)hexan-1-amine (TPHA), was synthesized via a Knorr-Paal reaction using 1,4-di(2-thienyl)-1,4-butanedione and hexane-1,6-diamine. The resultant monomer was characterized by Nuclear Magnetic Resonance (H-1-NMR). Electroactivity of TPHA was investigated via cyclic voltammetry. The electronic structure and the nature of electrochromism in P(TPHA) and its copolymer with EDOT, (P(TPHA-co-EDOT)), were examined via spectroelectrochem...
