METHOD FOR PREPARING OPTICALLY ACTIVE POLYANLINE Russian patent published in 2007 - IPC C12P13/00 C08G73/02 

FIELD: organic chemistry, polymers, chemical technology, biotechnology.

SUBSTANCE: method involves carrying out the oxidative polymerization reaction of aniline for a single step. Laccase that uses air molecular oxygen as a substrate is used a s catalyst for reaction wherein in process of this reaction oxygen is reduced to water. After carrying out the enzymatic polymerization reaction a formed polyaniline precipitate is separated from reaction solution, washed out with water and, if necessary, the dedoping process of emeraldin conducting polyaniline salt with ammonia aqueous solution is carried out. Advantage of method involves it's a single step in carrying out the process and ecological purity of the end product. Invention can be used in creature of bio- and chemosensors and separation of optically active compounds.

EFFECT: improved method of synthesis.
