Abstract
We propose that the supercritical fluid crystallization (SCFC) method is one of the most promising techniques for preparing organic microcrystals. In the case of titanylphthalocyanine (TiOPc) and diacetylenes, the size and forms of the resulting microcrystals could be controlled by changing SCFC conditions. In particular, the SCFC method for the microcrystallizaton of phthalocyanines is expected to be useful, replacing the previous acid-pasting method.Keywords
