  • Publication number: 20020114973
    Abstract: Provided is a new molecular compound excellent in luminous property, which has a molecular structure wherein a thiophene ring and a benzene (or naphthalene) ring are directly bonded to each other, as a molecular compound making it possible to control its luminous color relatively easily and realize highly efficient and bright luminescence. In this compound, its color tone of emitted light can be variously changed by altering the number of the thiophenering and the benzene (or naphthalene)-ring and the bonding order of the rings. Thus, if this molecular compound is used as a luminous material, it is possible to easily cope with both control of its luminous color and realization of highly efficient and bright luminescence. Use of a luminous material using this molecular compound makes it possible to realize luminescence having wide colors from violet to red highly efficiently.

  • Patent number: 5670607
    Abstract: This invention relates to compositions of miscible electrically conductive polyaniline and to conductive articles formed from such compositions. Specifically, the invention relates to polyaniline dioctylsulfosuccinate which is miscible with some common organic solvents. UV-Visible spectra of dilute solutions of this polymer show a linear dependence of absorbance on concentration. Solution with high concentrations of polymer, >50 w %, can be prepared and uniform films can be cast from these solutions without any loss in electrical conductivity. The solutions and films are stable.

  • Patent number: 5605993
    Abstract: It concerns a monomer, a polymer obtained from the monomer and a process for obtaining the said polymer. The monomer consists of a polyether containing at least 3 ether units and pyrrole or thiophene units bonded to the ends of the chains of this polyether via, for each of these heterocycic compounds, either their carbon atoms in the 3,3'-positions of their heterocycles or, as regards more particularly the pyrrole groups, via their respective nitrogen atoms, the 2- and 2'-positions of these heterocycles being, however, free of all substitutions or, at the very most, substituted by easily removable groups (protective groups, for example).Application to the purification and recovery of metal ions such as radioactive silver.

  • Patent number: 5561206
    Abstract: Disclosed is a copolymer represented by the following general formula (1): ##STR1## wherein R.sub.1 represents a group based on a polymer or a copolymer possessing electroconductivity and inducing coloration or discoloration on being oxidized or reduced, R.sub.2 and R.sub.3 represent independently a hydrogen atom or an alkyl group having 1 to 1,000 carbon atoms, A represents a group possessing polarity and exhibiting affinity for ions, and L and M are independently an integer of at least 1, providing that the total degree of polymerization is an integer in the range of 10 to 12,000. The copolymer may be a block copolymer or a random copolymer. This copolymer exhibits electrochromism and, therefore, is useful as a coloring-discoloring material which induces coloration or discoloration on being oxidized or reduced, particularly as an electrochromic substance used in an electrochromic display device.
