  • optoelectrochromic characterization and smart windows application of bi functional amid substituted thienyl Pyrrole Derivative
    Polymer, 2017
    Co-Authors: Tugba Soganci, Sevil Soyleyici, Hc Soyleyici
    Abstract:

    Abstract Because of some disadvantages of polythiophenes and polyPyrroles, alternatively thienylPyrrole monomers which include these two heterocycles in its structure have been synthesized for overcome optical, electrical and stability problems. However, the desired properties can only be achieved by the copolymerization of thienylPyrroles with EDOT. The optical, electrical properties and stability of the thienylPyrrole compounds have reached unique levels when using amide substituent Derivatives synthesized by our group for the first time. In this work, terephthalamide was used to synthesize double-sided, symmetric amide substituted thienyl Pyrrole. By doing so, we obtained a superstructure that provides three dimensional electrical conductivity and has much better optical, electrical properties and stability. Besides investigation of its optical and electrical properties, deposition of the polymer film on the electrode during electropolymerization and the ion mobility in the redox process were determined by EQCM. An electrochromic device has been constructed with this new type polymer to demonstrate the utility of its use in practical applications. As a result, it has been shown that the new type amide substituted thienyl Pyrrole Derivatives have promising usage for all practical applications of conductive polymers due to their unique properties such as high optical contrast, high stability and fast response time.

  • electrochemistry of secondary amine substituted 2 5 di 2 thienyl Pyrrole Derivative and its copolymer
    Journal of The Electrochemical Society, 2017
    Co-Authors: Ogun Gumusay, Hc Soyleyici, Tugba Soganci, Halil Cetisli
    Abstract:

    Since the discovery of conductive polymers, one of the most promising innovations in the field of polymer chemistry, these materials have been used in many practical applications. However, new monomers are being designed to overcome some of the disadvantages of conductive polymers, such as their inherent stability, low optical and electrical properties. It is known that minor arrangement on the monomer structure lead to very large changes in the polymer properties. In this study, a thienyl Pyrrole monomer, one of the most studied monomers in the field of conductive polymers, has been produced using hydrazine Derivatives instead of amines. For this purpose, the model monomer, N-phenyl-2,5-di(thiophen-2-yl)-1H-pyrrol-1-amine, was synthesized and the optical, electrochemical and electrochromic properties of its conductive polymer were investigated. Furthermore, copolymer studies with 3,4-ethylenedioxythiophene (EDOT) have been done to emphasize the importance of copolymerization on electrochromic properties of the conducting polymers. Effects of the feed ratio of the monomers and applied potential for copolymerization on optical and electrochemical properties of the electrochemically synthesized copolymers were investigated in detail.

  • Smart window application of a new hydrazide type SNS Derivative
    RSC Advances, 2016
    Co-Authors: Tugba Soganci, Emrah Giziroglu, Hc Soyleyici
    Abstract:

    In this article the smart window application of a new type of thienylPyrrole Derivative is presented. For this purpose, the new type of 2,5-di(2-thienyl)Pyrrole Derivative, which is named N-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)-4-(vinyloxy)benzamide (TPVB), has been prepared by the reaction of 1,4-di(2-thienyl)-1,4-butanedione and 4-(vinyloxy)benzohydrazide. Using hydrazine instead of amine in the synthesis process has significantly improved the related polymer's optical properties. Spectroelectrochemical investigations revealed that P(TPVB) is more durable with better long-term stability and has the lowest band gap compared with the other SNS Derivatives. A chronoamperometry experiment showed that the P(TPVB) polymer film has excellent redox stability, moderate switching time and high optical contrast. So it is possible to use this polymer with superior optical properties in smart window applications. A smart window based on P(TPVB) and poly(3,4-ethylenedioxythiophene) (P(EDOT)) was set up in a sandwich configuration. Optoelectrochemical investigations displayed that the reduced state of the device displays an orange color whereas it is blue for the oxidized state. The switching time and optical contrast (ΔT%) of the device at 625 nm are 1.0 s and 43%, respectively.

  • Fabrication of multifunctional 2,5-di(2-thienyl) Pyrrole based conducting copolymer for further sensor and optoelectronic applications
    'The Electrochemical Society', 2018
    Co-Authors: Soganci T, Soyleyici H.c., Ak M
    Abstract:

    In this work a multifunctional amid substituted 2,5-di(2-thienyl)Pyrrole Derivative (BTP), has been synthesized. The synthesized monomer has unique properties for improving the optical and electrical properties of its conductive polymer. The amide substitution in the monomers provides an effective delocalization of the π-bonds by forcing the conjugated thienylPyrrole electroactive group into the more planar structure. This improves the optical and electrical properties of the conductive polymer. Moreover, electropolymerization has resulted in a cross-linked conductive polymer with three-dimensional conductivity as the monomer structure contains two electroactive groups. Finally, the amine group in the structure allows for further functionalization of the conducting polymer and its use in various sensor platforms. Furthermore, the synthesized monomer (BTP) has been copolymerized with EDOT using different monomer feed ratios and the properties of the copolymer have been investigated in comparison with the homopolymer. Electrochromic devices have constructed with the obtained polymer and it has been determined that constructed device has a high optical contrast and stability when compared with other 2,5-di(2-thienyl)Pyrrole Derivatives in the literature. © 2018 The Electrochemical Society

  • A soluble and fluorescent new type thienylPyrrole based conjugated polymer: Optical, electrical and electrochemical properties
    'Royal Society of Chemistry (RSC)', 2016
    Co-Authors: Soyleyici H.c., Ak Metin
    Abstract:

    Recently, increased attention has been focused on the synthesis of soluble and processable conducting polymers due to interest in their potential application. For this purpose a new type electroactive 2,5-di(2-thienyl)Pyrrole Derivative was synthesized and its novel solution-processable and fluorescent polymer, namely poly(N-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)-3,4,5-tris(dodecyloxy)benzamide) (P(TPDOB)), was electrochemically synthesized. Characterization of the monomer and the polymer was performed by 1H-NMR, 13C-NMR, cyclic voltammetry, and UV-vis and fluorescence spectroscopy. This soluble polymer has very well-defined and reversible redox processes in the acetonitrile-lithium perchlorate (ACN/LiClO4) couple. Moreover, P(TPDOB) shows multielectrochromic behavior: blue in the oxidized state, caesious in the intermediate state and greenish in the neutral state. Also the copolymer consists of EDOT and TPDOB was synthesized by cyclic voltammetry. A copolymer film has superior electrochromic and electrical properties when compared with a homopolymer. Furthermore, the fluorescence features of the monomer and the polymer were investigated. Although the monomer is a violet light emitter, its polymer is a yellow light emitter. Synthesis of this new type solution-processable and fluorescent conducting polymer is an alternative to the conventional synthesis of soluble conducting polymers which allows the direct application of the conductive polymer to any desired surface for potential technological applications. © 2016 the Owner Societies
