METHOD OF DOPING ORGANIC POLYMER

摘要

PURPOSE:To produce an extremely stable organic material having highly electrical conductivity, by treating a linear high-molecular weight polymer having a specific quinonediimine structure with a protonic acid as a dopant. CONSTITUTION:A substantially linear organic polymer having a quinonediimine structure as a main repeating unit shown by the formula (R is H, or alkyl) is treated with a protonic acid having <=3.0pKa as an electron accepting dopant. An organic polymer having >=0.10 logarithmic viscosity in 0.5g/dl conc. sulfuric acid solution at 30 deg.C is used as the organic polymer. Aniline or an alkylaniline is subjected to oxidation polymerization with an oxidizing agent in a protonic acid-containing reaction medium (>=1.2 molar ratio of protonic acid/potassium dichromate) to give a precursor, which is chemically compensated, and treated with the protonic acid.
