Title:
METHOD FOR PURIFYING ORGANIC MATERIAL, MATERIAL FOR ORGANIC ELECTRONICS, PHOTOELECTRIC CONVERSION ELEMENT, OPTICAL SENSOR, IMAGING ELEMENT, AND ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/137741
Kind Code:
A1
Abstract:
A method for purifying an organic material, which can sublimate and purify an organic material having a high sublimation temperature and high heat resistance within a short time with high purity and high yield. The method comprises: reducing the concentration of inorganic impurities in an organic material to 5000 ppm or less, wherein the organic material has a temperature of 10% weight loss of 250˚C or higher as measured by thermogravimetry under a degree of vacuum of 1×10-2 Pa or less; and then sublimating the organic material, thereby purifying the organic material.
