摘要: Abstract The synthesis of a homologous series octaalkoxycarbonyl-substituted metal-free phthalocyanines (Pc) is described. mesomorphic properties these new materials were studied by differential scanning calorimetry (DSC), optical microscopy and X-ray investigations. All compounds show discotic mes-ophase in an extremely large temperature interval including room temperature. diffraction patterns the mesophases confirm that all form hexagonal columnar mesophase type Dho .
