摘要：

The crystal and mesophase transitions of the discotic material 5,10,15,20-tetrakis (4-n-dodecylphenyl)porphyrin have been studied by high pressure DTA and wide angle X-ray diffraction. At lower pressures, the discotic lamellar (D-L) phase is enantiotropic, but at higher pressures above a critical point determined as 240MPa and 170 degrees C the D-L phase is monotropic.
