A novel approach for the in situ synthesis of conjugated polyaniline-poly(ethylene glycol) graft copolymer (PA-g-PEG) by the combination of oxidative polymerization and copper catalyzed azide alkyne cycloaddition (CuAAC) click reaction is described. The method pertains to the reduction of the CuBr2 catalyst during the oxidative copolymerization of aniline and aminophenyl propargylether to Cu(I) species, which catalyze the CuAAC reaction between thus formed polyaniline with pendant alkyne groups and independently prepared azide functional PEG in both simultaneous and sequential manner. The obtained water-soluble (PA-g-PEG) was used for the construction of glucose biosensor by a simple one-step approach. Combined electrostatic polyanion-polycation and hydrogen bond interactions between (PA-g-PEG) and glucose oxidase provided a suitable immobilization matrix for the enzyme resulting in excellent analytical parameters. (PA-g-PEG) based glucose biosensor exhibited a remarkable response time, producing an instant signal upon addition of analyte, making this sensor an attractive alternative for the existing devices.

Atak, Samed; Icli-Ozkut, Merve; Önal, Ahmet Muhtar; CİHANER, ATİLLA (Wiley, 2011-10-15)
Optical and electrochemical properties of regiosymmetric and soluble alkylenedioxyselenophene-based electrochromic polymers, namely poly(3,3-dibutyl-3,4-dihydro-2H-seleno pheno [3,4-b][1,4]dioxephine) (PProDOS-C(4)), poly(3,3-dihexyl-3,4-dihydro-2H-selenopheno[3,4-b][1,4]dioxephine) (PProDOS-C(6)), and poly(3,3-didecyl-3,4-dihydro-2H-selenopheno[3,4-b][1,4]dioxephine) (PProDOS-C(10)), are highlighted. It is noted that these unique polymers have low bandgaps (1.57-1.65 eV), and they are exceptionally stable ...
Complex-radical cyclocopolymerization of allyl a-(N-maleimido)acetate with styrene and maleic anhydride
Rzaev, ZMO; Salamova, UU; Altindal, S (Wiley, 1997-08-01)
Radical copolymerizations of allyl alpha-(N-maleimido)acetate (AMI) with styrene (D, electron-donor) or maleic anhydride (A, electron-acceptor) were carried out in benzene and/or methyl ethyl ketone (MEK) at 50-70 degrees C in the presence of 2,2'-azoisobutyronitrile (AIBN) as initiator. The structure and properties of copolymers synthesized were derived from IR, chemical, DTA and TGA analyses. Side-chain unsaturation of macromolecules was also proved by the crosslinking effect observed. Kinetic parameters ...
Synthesis of ferrocenyl pyrazoles by the reaction of (2-formyl-1-chlorovinyl)ferrocene with hydrazines
Zora, Metin (Elsevier BV, 2007-10-15)
Synthesis of ferrocenyl-substituted pyrazoles via the reaction between (2-formyl-1-chlorovinyl)ferrocene and hydrazine derivatives is described. Depending upon the substitution pattern of hydrazine, the reaction affords 1-alkyl/aryl-5-ferrocenylpyrazoles and/or 1-alkyl/ aryl-3-ferrocenylpyrazoles. The reaction appears to be general for a variety of hydrazine derivatives.
A facile synthesis of various butenolides
Tanyeli, Cihangir (Informa UK Limited, 2000-01-01)
The synthesis of alpha'-acyloxy-alpha,beta-unsaturated cyclic ketones from the corresponding alpha,beta-unsaturated cyclic ketones by using manganese (III) acetate in combination with 2-chloropropionic acid followed by subsequent Arbuzov and intramolecular Horner-Emmons cyclization reactions provided a convenient synthetic pathway to various butenolides 4a-d.
Tuning of the neutral state color of the pi-conjugated donor-acceptor-donor type polymer from blue to green via changing the donor strength on the polymer
Tarkuc, Simge; Udum, Yasemin Arslan; Toppare, Levent Kamil (Elsevier BV, 2009-07-17)
Two donor-acceptor-donor types of T-conjugated monomers were synthesized using Stille coupling reaction. Both monomers were found to produce electroactive polymers upon electrochemical oxidation. The effects of different donor substituents on the polymers' electrochemical and spectroelectrochemical properties were examined. Optical characterization revealed that the band gaps of poly(2-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-3-(2,3-dihydrobenzo[b][1,4]dioxin-7-yl)-5,8-di(thiophen-2-yl)quinoxaline) (PDBQTh) an...
