We propose a new method of growing single crystals of organic molecular semiconductors, using melted anthracene as a solvent. The method is called the Repeated Solid Solvent Growth Method. Needle-like single crystals of Cu phthalocyanine up to 10 mm in length have been grown by repeated cooling of a glass ampoule which contains the anthracene melt dissolving the molecule. We have found that the crystals tend to grow larger as the procedure is repeated. The crystal growth process is discussed on the basis of the temperature gradient of the growing ampoule.
