摘要：

The phase transition characteristics of 9,10-di(2-naphthyl)anthracene (ADN), an organic light emitting diode (OLED) material, are evaluated under vacuum. The phase transition is indicated by a plateau in the temperature curve of the ADN upon heating to its melting or sublimation temperature under pressure in a vacuum chamber. The melting temperature of the ADN at 1 atm pressure is verified by differential scanning calorimetry. The boiling temperature decreases by a few degrees as the vacuum chamber is evacuated from 1 atmosphere, and the material sublimes below 1 Torr. The sublimation temperature also decreases slightly as the pressure is lowered. Our results provide not only the optimal evaporation conditions for ADN but also information on the thermal stability of ADN and other types of organic materials for OLEDs under high vacuum.
