  • Organic compound having an acetylene group, vacuum deposition polymerization thereof, deposited polymerized thin film, and electroluminescence device containing same
    Publication number: 20020018912
    Abstract: The present invention relates to an organic compound having acetylene group(s), a thin film formed by vacuum deposition polymerization using said organic compound, vacuum deposition polymerization to form said thin film, and an electroluminescence device containing said thin film. More particularly, the present invention relates to an organic compound having at least one acetylene groups, vacuum deposition polymerization in which said organic compound is deposited on the substrate and simultaneously or then polymerized by heat treatment or UV irradiation to form a polymer thin film, and an electroluminescence device using at least one layer of said thin film.

  • Conductive polymeric composite with high electrical activation density and method for preparing the same
    Patent number: 5416170
    Abstract: A conductive polymeric composite with an improved electrical activation density obtained by compounding a ferrocene derivative used as a dopant with a polypyrrole of a conductive polymer and a method for preparing the same. The conductive composite can be produced by use of a chemical method or an electrochemical method. In the case of using the chemical method, pyrrole or its derivative is dissolved in a solution containing a ferrocene derivative, together with one or mixture of ferric trichloride, ammonium persulfate and copper chloride-aluminum chloride. In the case of using the electrochemical method, a solution, in which pyrrole or its derivative is dissolved together with ferrocene derivative, is used, as an electrolytic solution, alone or together with a solution in which an electrolyte of inorganic salt such as ammonium salt, lithium perchloric acid and tetraalkylammonium perchloric acid is dissolved.
