We propose a new method of growing single crystals for the organic molecular semiconductors, using melted anthracene as a solvent. Single crystals of N,N′-dimethylperylene-3,4 : 9,10-bis(dicarboximide) up to 5 mm in length have been grown by cooling a glass ampoule which contains the anthracene melt dissolving the molecule. The crystal growing process is discussed on the basis of the phase diagram and the temperature gradient of the growing ampoule. Application to other materials proves that this method is useful to obtain single crystals of functional molecules, at temperatures much lower than the melting point or sublimation point of the materials.
