A new fluorenone based soluble polymer, namely poly(2,7-bis-(3,3-dihexyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepin-6-yI)-fluoren-9-one) (PPFP), containing propylenedioxythiophene (ProDOT) as a donor and fluorenone (FO) as an acceptor group is highlighted. Electrochemical polymerization of 2,7bis-(3,3-dihexyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepin-6-yI)-fluoren-9-one (PFP) was achieved in dichloromethane/acetonitrile mixture with 0.1 M tetrabutylammonium hexafluorophosphate via potential cycling. The polymer shows an electrochromic behavior, a color change from orange to dark blue during oxidation with a high coloration efficiency (422 cm(2)/C at 684 nm) and orange to yellow during reduction with high optical and electrochemical stability as compared to its close analogues, in addition it is found to be both p and n dopable. Furthermore, this soluble polymer exhibits fluorescent properties (the emission of orange light (578 nm) in THF solution).

A novel electrically conducting polymer, poly(2-dodecyl-4,7-di(selenophen-2-yl)benzotriazole) (Poly(SBT)), containing selenophene as a strong donor and benzotriazole as a strong acceptor group was synthesized by electrochemical polymerization. Homopolymerization and copolymerization ( in the presence of 3,4-ethylenedioxythiophene (EDOT) ) was achieved in acetonitrile/ dichloromethane(95/5 v/v) with 0.1M tetrabutylammonium hexafluorophosphate (TBAPF6). The electrochemical and optical properties of homopolyme...

The optical and electrochemical properties of a regioregular and soluble alkylenedioxyselenophene-based electrochromic polymer, namely poly(3,3-didecyl-3,4-dihydro-2H-selenopheno[3,4-b][1,4] dioxepine (PProDOS-C-10), which is synthesized by electrochemical polymerization, are highlighted. It is noted that this unique polymer has a low band gap (1.58 eV) and is exceptionally stable under ambient atmospheric conditions. Polymer films retain 97% of their electroactivity after 40 000 cycles. The percentage tran...
A unique processable green polymer with a transmissive oxidized state for realization of potential RGB-based electrochromic device applications
Günbaş, Emrullah Görkem; Toppare, Levent Kamil (2008-07-23)
Realization of commercial RGB-based polymer electrochromic-device applications can only be achieved by processable materials that possess three complementary colors in the reduced state and are transparent in the oxidized state. This report highlights the synthesis of the first processable green polymer with a transmissive oxidized state. The polymer revealed superior optical contrast in the visible region with fast switching times and robust stability. Hence, this material is the outstanding candidate for ...

The reaction between 1,5-diethenylnaphthalene and sec-butyllithium produces a new difunctional organolithium initiator which is soluble in non-polar solvents and effective in the synthesis of styrene-isoprene-styrene triblock copolymer. Monomodal molecular weight distributions are observed for block copolymers and styrene homopolymers. The microstructure of polyisoprene blocks is similar to those polymers initiated by butyllithium in the same solvent.
A New Amperometric Biosensor for Diamine: Use of a Conducting Polymer Layer
Al Layla, Alaa M. T.; Turkarslan, Ozlem; KURBANOĞLU, SEVİNÇ; Sulaiman, Saddalah T.; Al-Flayeh, K. A.; Toppare, Levent Kamil (2013-01-01)
Diamine oxidase (DAO) from Porcine kidney E.C. is used for the amperometric detection of biogenic amines. Immobilization of enzyme is performed via entrapment in conducting poly (3,4-ethylenedioxythiophene) during electrochemical polymerization. The responses of the enzyme electrodes are measured via monitoring current at +0.7 V. In order to minimize the common interferences, an over oxidized film of polypyrrole is introduced to the electrode. Thickness of the film, kinetic parameters, substrate spe...
