    Abstract: PURPOSE:To provide a production process of poly-2,5-pyridinediylvinylene in which the sulfonium salt elimination process problematic in its inapplicability to industrial production is not used, a monomer stable at room temperature is used as the monomer used in the polymerization, the polymer is easily formed, and the polymer is easily purified, and which is suited for industrial production. CONSTITUTION:A 2,5-dihalomethylpyridine is polymerized in the presence of a base by a process of polymerization through dehydrohalogenation to obtain a polymer represented by the formula. The obtained polymer is subjected to heat treatment at 230-300 deg.C in a nitrogen or inert gas stream or in a vacuum to eliminate the residual halogen part of this polymer and to thereby improve the convertion into the polymer.

    Abstract: NEW MATERIAL:The pyrrole compound of formula (R is higher alkyl). EXAMPLE:3-Octylpyrrole. USE:The polymer of the compound is useful as an organic conductive polymer. PREPARATION:The objective compound of formula can be produced by acylating N-sulfonated pyrrole with a carboxylic acid chloride in the presence of a Friedel-Crafts catalyst, desulfonating the reaction product, separating an alkyl-3-pyrrolyl ketone from the obtained mixture of 2-substituted pyrrole and 3-substituted pyrrole and purifying and reducing the separated ketone. The Friedel-Crafts catalyst is e.g., stannic chloride or aluminum chloride and the reducing agent is aluminum lithium hydride, etc.

    Abstract: PURPOSE:To obtain a specified thiophene polymer in a neutral state and an organic semiconductor in the form a film which is excellent in heat resistance and smoothness, stable in air and useful as a display material and can be obtained without molding, by doping said polymer with an anion. CONSTITUTION:A compound of formula I, for example, synthesized by adding a Grignard reagent obtained by, for example, reacting 2-bromothiophene with metallic Mg to 2,5-dibromothiazole and condensing the mixture together with a supporting electrolyte comprising an anion-forming substance such as tetrafluoroborate, perchlorate, hexafluorophosphate, halide, SO4 or trifluoroacetate ion is electrolytically polymerized in a polar solvent such as propylene carbonate by using gold, platinum or the like as an electrode at a controlled electric quantity in an inert atmosphere. In this way, an anion-doped thiophene of repeating units of formula II (wherein R is a group of formula III, IV or V) having an electric conductivity of 10 -10 S/cm and a desired film thickness can be obtained. If desired, this polymer is converted into a thiophene polymer in a neutral state by removing the dopant by reversing the polarity.
