Disclosed is a purification apparatus and method. The purification apparatus includes: a mobile phase distillation part for distilling a mobile phase; a mobile phase liquefaction part for liquefying the distilled mobile phase; and a purification part disposed between the mobile phase distillation part and the mobile phase liquefaction part, for mixing the mobile phase liquefied at the mobile liquefaction part with to-be-purified material, removing impurities from the mixture through a bonded phase, and sending the impurity-removed purified material to the mobile phase distillation part.
摘要:
An organic electroluminescent (EL) device is provided which uses an electron-transport layer including hole blocking capability. The device includes a stack structure, with an emitting layer and an electron-transport layer provided between an anode and a cathode. The electron-transport layer is a mixture of at least two materials. This mixture may include an organic compound and one or more other organic compounds, or may include a metal or inorganic compound and one or more other metal or inorganic compounds, or may include one or more organic compounds and one or more metal or inorganic compounds. By incorporating a hole blocking capability into the electron-transport layer, structure and fabrication of the device is simplified and efficiency is increased.
