1975 International Electron Devices Meeting, 1975
The development of a solid state electro-chromic device for display applications is reported in this paper. The electro-chromic structure consists of a multilayer thin film system and therefore, successful fabrication of it requires optimization of each constituent layer with respect to various deposition parameters. We discuss the physical principle, the fabrication methods and operational characteristics of a typical system. Some ...

Summary form only given. The electrochemical and spectroelectrochernical studies of polypyrrole-latex coatings of 1 or 3 /spl mu/m thickness, on ITO windows in aqueous and organic media indicate a low electrochrornic effect and a strong capacitive effect. The best contrast was close to 0. 15 unit of absorbance and the average capacitance was 7.5 mF.cm/sup -2//spl mu/m/sup -1/. The range ...

We developed an electrochromic voxel array for realizing a three-dimensional (3D) display. A voxel is a unit of 3D graphic data just as a pixel of 2D data. The color of voxels is tuned not by their light emission but by their light absorption in the same way as the coloration of things in the real world. Our voxels consist ...

The development of a solid state electro-chromic device for display applications is reported in this paper. The electro-chromic structure consists of a multilayer thin film system and therefore, successful fabrication of it requires optimization of each constituent layer with respect to various deposition parameters. We discuss the physical principle, the fabrication methods and operational characteristics of a typical system. Some of the other systems involving "super-ionic conductors" and impurity doped systems are also considered.
In this research, we present a chip based capillary electrochromatography (CEC) carrying out a highly efficient separation of biomolecules through gradient hydrophobic stationary phase (GHSP) provided by multiwalled carbon nanotubes (MWCNTs) nanocolumns. 4-azidoaniline was employed for the surface modification of the MWCNTs to form a gradient stationary phase by a photochemical reaction through a gradient light filter. This device was used for separating proteins (20 ¿M FITC-BSA and FITC-Cytochrome C) with different hydrophobic characteristics, and MALDI-TOF-MS detection was employed to verify the separation efficiency in this MWCNTs nanocolumn. The best separation resolution of the FITC-BSA column efficiency was 2.5 × 10<sup>4</sup> (plats/m).
Summary form only given. The electrochemical and spectroelectrochernical studies of polypyrrole-latex coatings of 1 or 3 /spl mu/m thickness, on ITO windows in aqueous and organic media indicate a low electrochrornic effect and a strong capacitive effect. The best contrast was close to 0. 15 unit of absorbance and the average capacitance was 7.5 mF.cm/sup -2//spl mu/m/sup -1/. The range of potential to have a stable behaviour was 1 V. The response time was mostly function of the electrolyte conductivity. The RC constant was from 0.23 s for a film of 1 /spl mu/m in acetonitrile 0.25 M LiClO/sub 4/ to 3.1 s in propylene carbonate 0.3 M LiClO/sub 4/. Electrolyte influence was studied by chronocoulometry in water: HiClO/sub 4/, NiClO/sub 4/; H/sub 2/SO/sub 4/, Na/sub 2/SO/sub 4/; H/sub 3/PO/sub 4/; in propylene carbonate and acetonitrile LiClO/sub 4/. The stability of polypyrrole coatings was studied upon repetitive cyclic voltammetry. The best result was obtained in propylene carbonate. Films only lost 2.5% of charge (C) after 7000 cycles. Polypyrrole- latex coatings have no interest for electrochromic devices by itself, but it can be used as a first conducting layer for displays or electroluminescent diodes. Polypyrrole latex is also very interesting for condensers and for high power capacitors.
We developed an electrochromic voxel array for realizing a three-dimensional (3D) display. A voxel is a unit of 3D graphic data just as a pixel of 2D data. The color of voxels is tuned not by their light emission but by their light absorption in the same way as the coloration of things in the real world. Our voxels consist of ITO electrodes on glass substrates and 1 mm cubes of an UV- curing polymer coated with electrochromic material which can change its color electrically. We utilized poly-(3,4-ethylenedioxy- thiophene):polystyrenesulfonate (PEDOT:PSS) as the electrochromic material. Our voxel array and its Al counter electrode were soaked in CaCl<sub>2</sub> solution. Voxels were operated with a very low voltage of about 1.0 V We demonstrated a 4x4 voxel array, and the color change of the voxels was observed not only in the top view but also in the side view.
The polythiophenes have been widely used as a conducting polymer and in many others applications such as electrochromism. The introduction of an azobenzene group can extend the possible applications to other fields, such as optical memories. In this work, a thiophenic monomer with an azobenzene moiety at the 3-position of the thiophene ring was synthesized by esterification reaction between the commercial dye disperse red 1 (DR1) and 3-thiopheneacetic acid. The UV-Vis spectra of polymer in solution were obtained and used to study the possible solvato- and thermochromic properties of the polymer. The thermochromic property was analyzed in the temperature interval of 10 to 70 /spl deg/C. The solvents used in the solvatochromic study were hexane, chloroform, tetrahydrofuran, toluene, acetone, methanol, acetonitrile and dimethylformamide.
An all solid inorganic thin film electrochromic display with the complementary structure of /ITO/WO/sub 3//LiNbO/sub 3//NiO/ITO/ was fabricated. The layers of the display were all prepared by reactive magnetron sputtering. Electrochromic property measurements were performed on each active layer as well as on the assembled display. The display has been found to exhibit excellent display characteristics.
Summary form only given.Molecular J-aggregates are attracting the interest of many scientists as photoactive materials based on molecular excitons. The excitonic transition of the J-aggregates has a large oscillator strength characterized by one-dimensional systems, which results in an enhanced optical nonlinearity. Previously, we developed a vertical spin-coating method to prepare oriented J-aggregates dispersed in polyvinylalcohol (PVA) films. The new method enabled us to investigate detailed structure of J-aggregates. In the present paper, the molecular stacking and the number of molecules in a one-dimensional J-aggregate were determined by means of dichroic electrochromism (DCE). The dye molecule studied is tetraphenyl porphyrin sulfonic acid, information about which may offer a very important clue to the light-harvesting mechanism in a system of antenna chlorophyll.
Summary form only given. Cyclic voltammograms of methoxy, ethoxy and 2,5-dimethoxy substituted polyaniline in media of various pH show two redox waves between -0.2V to 0.8 V. A third wave appears between these two waves if the scanning potential is high or in medium of higher pH. According to the results of molecular weight determination by GPC, the third redox wave was attributed to the degradation products during hydrolysis. Epr and UV-visible spectra indicate the existence of radical in the potential range between the two redox waves. The higher the pH of the medium, The wider the potential range where the radical is stable. The larger the alkoxy group, the narrower the range where the radical is stable. The potential range where the radical is stable shifted to lower potential for 2,5-dimethoxy substituted polyaniline. Both monomer concentration and rate of synthesis affect the morphology of ethoxy-substituted polyaniline. Regular short fiber structure was formed under low current density when the monomer concentration is low. When monomer concentration is high, short regular fiber structure were always formed under high or low current densities. The regular short fiber structure was formed under slow growing rate.
Summary form only given. We report the dehalogenative polymerization of methyl 1, 4-dichloro- benzoate (MDCB) and methyl 2,5-dichlorothiophene carboxylate (MDCTC), and its hydrolysis to poly(sodium paraphenylene carboxylate) (PSPC) and poly(sodium thiophene-3-carboxylate) (PSTC) that are useful for the electrochemical polymerization of pyrrole. The degree of polymerization of PMPC and PMTC were 40 and 18, respectively. These polymers were soluble in water. Electrochemical polymerization of pyrrole was carried out in water with PSPC and PSTC, and the conductivities of polypyrrole films were 1.3 and 0.24 S/cm, respectively. By using PSPC and PSTC gave conducting films, it is suggested that PSPC and PSTC are interesting polymeric electrolytes.
