Production of five-membered heterocyclic compound polymer

Abstract

Abstract PURPOSE:To obtain a five-membered heterocyclic compound polymer in membrane form, by mixing a five-membered heterocyclic compound monomer with one of two solvents immiscible with each other, dissolving an acid or an oxidizing agent in the other solvent and bring these solvents into contact with each other in a stationary state. CONSTITUTION:Two solvents immiscible with each other are used, and a five- membered heterocyclic compound monomer is mixed with one of them while an acid or an oxidizing agent is dissolved in the other solvent. By bringing these solvents into contact with each other in a stationary state, a five- membered heterocyclic compound polymer in the form of a membrane or a gel is formed at the interface. Examples of combinations of the solvents used include those of solvents essentially immiscible with each other, such as water/ hexane and water/chloroform and a combination of solvents which separate into two layers by a difference in specific gravity, such as chloroform/pentane. Examples of the five-membered heterocyclic compounds include pyrrole, thiophene, selenophene, tellurophene and their derivatives.
