Synthesis and characterization of a novel polyphosphazene and its application to biosensor in combination with a conducting polymer
Ucan, Didem; Kanik, Fulya Ekiz; KARATAŞ, YUNUS; Toppare, Levent Kamil (Elsevier BV, 2014-10-01)
An amperometric glucose biosensor was prepared successfully based on a conducting polymer, poly(4-(2,5-di(thiophen-2-y1)-1H-pyrrol-1-yl)benzenamine) (poly( SNS-NH2)) and a flexible hydrophilic polyphosphazene polymer, poly[(methoxyethoxy)ethoxy-co-3-formylphenoxy]phosphazene (PPA). Poly( SNS-NH2) was electrochemically polymerized on a graphite electrode to achieve a conducting immobilization matrix to improve the enzyme immobilization on the transducer surface. Moreover, to strengthen the immobilization, a ...
Synthesis and characterization of alternating copolymers of thiophene-containing N-phenyl maleimide and styrene by photoinduced radical polymerization and their use in electropolymerization
Yilmaz, F; Cianga, L; Guner, Y; Topppare, L; Yagci, Y (Elsevier BV, 2004-08-05)
A novel N-(4-(3-thienyl methylene)-oxycarbonylphenyl) maleimide (MBThi) monomer was synthesized by the esterification reaction of maleimidobenzoic acid (MBA) with 3-thiophene methanol. Photoinduced radical polymerization was employed to prepare the alternating copolymers of MBThi with styrene (St) at room temperature using omega,omega-dimethoxy-omega-phenylacetophenone (DMPA) as photoinitiator. Different copolymerization conditions were examined to estimate the influence of the used solvents and comonomers'...

A series of new fluorene derivatives bearing pendant quinoxaline moieties with different donor groups, namely 5'H-spiro[fluorene-9,4'-pyrrolo[1,2-alquinoxaline] (FQ), 2,7-di(thiophen-2-yl)-5'H-spiro[fluorene-9,4'-pyrrolo[1,2-a]quinoxaline] (TQT), 2,7-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-5'H-spiro[fluorene-9,4'-pyrrolo[1,2-a]quinoxaline] (EQE) and 2,7-bis(3,3-dihexyl-3,4-dihydro-2H-thieno[3,4-b][1,4)dioxepin-6-yl)-5'H-spiro[fluorene-9,4'-pyrrolo[1,2-a]quinoxaline] (PQP) were synthesized. The monomer...
Synthesis and electropolymerization of a new ion sensitive ethylenedioxy-substituted terthiophene monomer bearing a quinoxaline moiety
Carbas, Buket Bezgin; Kivrak, Arif; Zora, Metin; Önal, Ahmet Muhtar (2012-07-15)
A new terthienyl based fluorescent polymer bearing pendant quinoxaline moieties directly attached to the 3-positions of the central thiophene ring was synthesized by electrochemical polymerization of 4-(2,5-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)thiophen-3-yl)Pyrrolo[1,2-a]quinoxaline (EE-Q). The corresponding polymer, poly(4-(2,5-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)thiophen-3-yl)pyrrolo[1,2-a]quinoxaline) P(EE-Q), was characterized by cyclic voltammetry, FT-IR and UV-vis spectroscopy. The po...
Synthesis and characterization of solvent free alkyd resin with hyperbranched melamine core
Keskin, Nagehan; Gündüz, Güngör; Çolak, Üner; Department of Chemical Engineering (2011)
The use of volatile organic compounds (VOC) in coating materials has adverse effects on both human health and the environment. Due to concern over these problems, coating industry has attempted to decrease the solvent contents of coating materials for the last three decades by developing water dispersed and powder paints. A recently developed method to make solvent free paint is to use highly branched polymers in high solid alkyd resins. Highly branched polymers help to achieve resins with viscosity much lo...
