摘要: Abstract The mesomorphic behavior of octa (dodecyloxymethyl) phthalocyanine was studied with DSC, optical microscopy, and X-ray diffraction. Two discotic mesophases were observed as a function temperature. Their structure corresponds to the piling up flat molecules in columns which are laterally assembled according two-dimensional hexagonal lattice (D = 31.2 A). repeat distance along found be about 4.5 A. low-temperature phase showed an extra sharp reflection at 20.5 A, indicating further ordering molecules.
