Synthesis of a novel, high-performance blue to transmissive switching electrochromic material is described. The polymer (P1) was prepared by both electrochemical (P1E) and chemical (P1C) means from the corresponding monomer. The electrochemically synthesized polymer (P1E) revealed 64% optical contrast change (on ITO) in the visible region and very fast switching times of 0.32 s (coloration) and 0.90 s (bleaching). On the other hand, the chemically synthesized, solution processable polymer (P1C) also showed a high optical contrast value (49%, on ITO) with very fast switching times of 0.86 s for coloration and 0.57 s for bleaching. These high optical contrast values coupled with fast switching times place these materials along with high-performance blue to transmissive electrochromic polymers. Significantly, these improved characteristics were achieved by side chain engineering of a known, inferior blue to transmissive polymer, PBEBT. Towards fabrication of flexible electrochromic devices, the performance of P1C was also tested on silver nanowire network electrodes. Even though the full potential of the material could not be demonstrated, a good optical contrast of 24% was achieved using these electrodes. Under the same potential range allowed by silver nanowire network electrodes, P1C on ITO showed an optical contrast of 30%. (C) 2017 Wiley Periodicals, Inc.

A Novel Near-IR Effective Pyrene-Based Donor-Acceptor Electrochrome Sefer, Emre; HACIOGLU, Serife O.; Tonga, Murat; Toppare, Levent Kamil; Çırpan, Ali; KOYUNCU, SERMET (2015-04-01) In this work, a novel donor-acceptor electrochromic monomer (3HTP), containing a pyrene subunit connected to a quinoxaline acceptor bridge, is synthesized. The corresponding polymer, poly-(3HTP), is directly deposited onto an indium tin oxide (ITO)/glass surface via an electrochemical process. Atomic force microscopy (AFM) images reveal that the electrochemically deposited poly-(3HTP) has a smooth surface due to self-assembly of the planar pyrene subunit. Electrochemical and optical properties are investiga...
Novel benzodithiophene type low band gap polymer solar cell application and device stability study with atomic layer deposition encapsulation technique Turkmen, Tulin Ate; Ozturk, Soner; Çırpan, Ali; YERLİ, Yusuf; Aslan, Emre; Mucur, Selin Piravadili; Parlak, Elif Alturk (IOP Publishing, 2019-10-01) Novel benzodithiophene type copolymer was synthesized through a solvent evaporation technique. Poly(5-(5-(4, 8-bis((2-ethylhexyl)oxy)benzo[1,2-b:4, 5-b']dithiophen-2-yl)thiophen-2-yl)-2, 3-bis(3, 4-bis(decyloxy)phenyl)-8-(thiophen-2-yl) quinoxaline) (P-TQTBDT) solar cells were encapsulated with conventional and Atomic Layer Deposition (ALD) techniques. Characterizations of the samples were carried out via nuclear magnetic resonance (NMR), gel permeation chromotagraphy (GPC) and cyclic voltammetry (CV) techn...
A novel multi-electrochromic polymer based on selenophene and benzotriazole via electrochemical and chemical polymerization Demir, Fatma; Keles, Duygu; Karabag, Aliekber; Çırpan, Ali; Toppare, Levent Kamil (Informa UK Limited, 2019-03-04) In this study, a novel donor-acceptor type monomer was designed based on selenophene and benzotriazole with a bulky pendant group and synthesized through Stille coupling reaction. The monomer was polymerized electrochemically by using cyclic voltammetry and also chemically by oxidation in the presence of FeCl3. Both polymers were then compared in terms of their optical properties, electrochemical and spectroelectrochemical behaviors, kinetic and colorimetric properties and surface morphologies. Independent ...
A new blue light emitting and electrochromic polyfluorene derivative for display applications Carbas, Buket Bezgin; Asil Alptekin, Demet; Friend, Richard H.; Önal, Ahmet Muhtar (2014-02-01) A novel blue emitting and electro-chromic conjugated copolymer based on 9,9'dioctylfluorene (F8) and spiro(fluorene- 9,9'-xanthene) (SFX) has been prepared. Optical, photophysical and electrochemical characterizations are given for the synthesized polymer; poly[spirofluorene-co-9,9'dioctylfluorene] P(F8-SFX). Switching of the corresponding polymer between yellow and purple states is demonstrated, and blue emission with Commission Internationale de L'Eclairage (CIE) coordinate at (0.19, 0.15) is obtained fro...
A novel conducting polymer based on terthienyl system bearing strong electron-withdrawing substituents and its electrochromic device application Asil Alptekin, Demet; Algı, Fatih; Önal, Ahmet Muhtar (Elsevier BV, 2008-7) A novel conducting polymer bearing strong electron-withdrawing substituents (EWS) directly attached to the 3,4-positions of the thiophene ring was synthesized by electrochemical polymerization of diethyl 2,5-di(thiophen-2-yl)thiophene-3,4-dicarboxylate (SSS-Diester). The polymer (PSSS-Diester) was characterized by cyclic voltammetry, FT-IR and UV-vis spectroscopy. The polymer has a reversible redox process and demonstrates a stable electrochromic behavior: reddish orange in the neutral state, brown in the i...
