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 from PLED device. The addition of a thin polymer interlayer ((F8) (0.5)-(TFB)(0.5)) is further investigated to maintain color purity. Furthermore, all polymer electrochromic device (ECD) based on P(F8-SFX) and poly(ethylene dioxythiophene) (PEDOT) was constructed. Spectroelectrochemistry and switching ability of the device were also investigated by UV-vis spectroscopy.

A New High-Performance Blue to Transmissive Electrochromic Material and Use of Silver Nanowire Network Electrodes as Substrates
YÜKSEL, Recep; ATAOGLU, Emre; TURAN, Janset; ALPUGAN, Ece; HACIOGLU, Serife Ozdemir; Toppare, Levent Kamil; Çırpan, Ali; Ünalan, Hüsnü Emrah; Günbaş, Emrullah Görkem (2017-05-15)
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 sensitive fluorescent chemosensor for anions based on a styryl-boradiazaindacene framework
Coskun, Ali; Deniz, Erhan; Akkaya, Engin U. (Elsevier BV, 2007-07-30)
Long wavelength emitting, extended conjugation boradiazaindacenes are novel dyes with considerable ICT character. By appending a dipicolylaminylethylamine group, the parent compound was transformed into a fluorescent dye with a strong chelating ability for Zn(II) ions. The zinc complex which has bright orange fluorescence, reversibly signals anions with very large changes in both the absorption and the emission spectra. The remarkable change in the emission intensity is explained in relation to the electron...
synthesis of a novel series of furan and fluorene containing monomers and their polymers
Güneş, Arzu; Önal, Ahmet Muhtar; Cihaner, Atilla; Department of Polymer Science and Technology (2011)
In this study, a novel series of conjugated monomers containing furan and fluorene units; 2,7-di(furan-2-yl)-9H-fluoren-9-one (FOF), 2-(2-(furan-2-yl)-9H-fluoren-7-yl)furan (FFF), and 2-(2-(furan-2-yl)-9,9-dihexyl-9H-fluoren-7-yl)furan (FHF) were synthesized and their electrochemical polymerization were achieved via potential cycling. Optical and electrochemical properties of the polymers, poly(2,7-di(furan-2-yl)-9H-fluoren-9-one) (PFOF), poly(2-(2-(furan-2-yl)-9H-fluoren-7-yl)furan (PFFF) and poly(2-(2-(fu...
Novel donor-acceptor type polymers towards excellent neutral state green polymeric materials for realization of RGB based electrochromic device applications
Günbaş, Görkem Emrullah; Toppare, Levent Kamil; Department of Chemistry (2007)
Polymers having one of the three complementary colors (red, green, and blue) in the reduced state and high transmissivity in the oxidized state are key materials towards use in electrochromic devices and displays. Although many neutral state red and blue polymers were reported up to date, neutral state green polymeric materials appear to be limited. For potential application of electrochromic materials in display technologies, one should have to create the entire color spectrum and this can be only achieved...
A neutral state green polymer with a superior transmissive light blue oxidized state
Durmus, Asuman; Günbaş, Emrullah Görkem; Camurlu, Pinar; Toppare, Levent Kamil (2007-01-01)
This report highlights the synthesis of only the second green polymer in the literature, which possesses superior properties over the first: a highly transmissive light blue color in the oxidized state with high optical contrast and excellent switching properties.
