“…Figures 2 and 3 show cyclic voltammograms of P(TTPP) and P(TTPP-co-EDOT) at different scan rates. The current responses were directly proportional to the scan rate, indicating that the polymer films were electroactive and well adhered to the electrode [22,33]. The scan rates for the anodic and cathodic peak currents show a linear dependence as a function of the scan rate as illustrated in the insets of Figs 2 and 3 for P(TTPP) and P(TTPP-co-EDOT), respectively.…”

A new polythiophene derivative was synthesized by electrochemical oxidative polymerization of 2,5-di(thiophen-2-yl)-1-(4-(thiophen-3-yl)phenyl)-1H-pyrrole (TTPP). The structure of the monomer was evaluated by 1 H-NMR and FT-IR. The polymer (P(TTPP)) and its co-polymer with 3,4-ethylenedioxythiophene (P(TTPP-co-EDOT)) were synthesized via potentiostatic electrochemical polymerization. The resulting polymers were characterized by cyclic voltammetry (CV), FT-IR, SEM and UV-Vis spectroscopy, and conductivity measurements. Also, the spectroelectrochemical and electrochromic properties of P(TTPPco-EDOT) were investigated. While P(TTPP) reveals no electrochromic activity, its co-polymer with EDOT has two different colours (yellow and blue). Optical contrast, switching time, λ max and band gap (E g ) of (P(TTPP-co-EDOT)) were determined.

“…As seen from the transmittance data, the copolymer formation results with higher T% values with increasing CzPDICz ratio in the co-monomer mixture. [42] However, the inverse trend was observed for their high energy bands. At their high energy bands, the transmittance percents were found as 15, 14, and 11% for P(9:1), P(4:1), and P(1:1), respectively, further indicating the increasing amount of CzPDICz contribution in the copolymers.…”

A new copolymer of 3,4-ethylenedioxythiophene (EDOT) and 5-(2-ethylhexyl)-1,3-bis(9-methyl-9H-carbazol-3-yl)-5H-thieno [3,4-c]pyrrole-4,6-dione (CzPDICz) was electrochemically synthesized using different monomer feed ratios. The resulting copolymer films were investigated in terms of their electrochemical and electro-optical behaviors. Properties of the obtained copolymer films through different monomer feed ratios were compared to each other and to individual poly(ethylenedioxythiophene; PEDOT) and homopolymer of CzPDICz in order to observe the differences in the properties with respect to PEDOT and P(CzPDICz). Copolymers exhibited well adherence on the electrode surface with having non-diffusional redox process. The monomer feed ratios were prepared as 9:1; 4:1, and 1:1 (EDOT:CzPDICz) and changes in the electrochemical and spectroelectrochemical behavior were noted with increasing CzPDICz ratio in the monomer mixture. Although no appreciable change in the optical band gap values of the copolymers was noted as compared to PEDOT, the neutral blue copolymers exhibited grayish color in their semioxidized states and transparent green in their fully oxidized states.

“…A tool to improve the formation of a uniform and well adhered film electrodeposited onto the electrode surface is its copolymerisation with another monomer that presents some other desired property. Therefore electrochemical copolymerisation is an efficient approach for the modification of the properties of DHQT and then to obtain a variety of conjugated polymers with different electrical, optical and morphological properties [23][24][25]. In order to modify the properties of DHQT and thus enhance the adherence and film formation capability of this polymer, this work has focused on the electrochemical copolymerisation of DHQT with a pyrrole derivative, (R)-(-)-3-(1-pyrrolyl)propyl-N-(3,5-dinitrobenzoyl)-α-phenylglycinate, DNBP.…”
