APPARATUS AND METHOD FOR ULTRA-HIGHLY PURIFYING ORGANIC MATERIALS FOR OLED PURIFIED BY IONIC LIQUIDS

摘要

The present invention relates to an apparatus and method for ultra-highly purifying organic materials for an OLED purified by ionic liquid. The present invention has advantages of enhancing purity of the organic materials up to greater than or equal to 99.99% by removing cations and anions which are ionic liquid molecules in trace amounts attached onto a surface of the organic materials by means of a removing unit while continuously stirring the organic materials for the OLED purified by using ionic liquid as a liquid filter.
