摘要： Disclosed is an improved sublimation method for the purification of organic small molecules. The new method features that barriers are applied in the collection region of sublimation tube so that the gas flow path is modified to pass through or bypass the barriers from the heating region to the vacuum pump. The arrangement of the barriers can effectively separate the main product from the impurities. The main product is enriched in a collection region, while the volatile impurities are enriched in an impurity region. This method has been proved to improve the quality of sublimed materials substantially according to the purity measurements and OLED performance tests.

摘要： The invention relates to a sublimation purification apparatus and a method for purifying a material for an organic light-emitting diode (OLED). Conventional sublimation purification apparatuses are batch type, where one sublimation purification process is performed by loading one source material into the processor chamber, and then unloading a purified material from the process chamber. These processes are manually performed, and thus it is not possible to continuously produce the purified material for the OLED. Therefore, it is difficult to increase a throughput and productivity. According to the invention, loading the source material and unloading the purified material are performed automatically, thus enabling a continuous process of purifying the source material for the OLED.

摘要： There is provided a film formation apparatus which is capable of forming an EL layer using an EL material with high purity. The EL material is purified by sublimation immediately before film formation in the film formation apparatus, to thereby remove oxygen, water, and another impurity, which are included in the EL material. Also, when film formation is performed using the EL material (high purity EL material) obtained by purifying with sublimation as an evaporation source, a high purity EL layer can be formed.
