Supercritical fluid crystallization (SCFC) method is proposed for preparing microcrystals of π-conjugated organic compounds as a development of conventional reprecipitation method. In SCFC method, both size and form of titanylphthalocyanine microcrystals could be controlled by changing experimental conditions such as temperature and type of solvent. We have been able to fabricate γ-form of titanylphthalocyanine microcrystals with 50 nm in size, which is expected to be promising material for organic photoconductors.
