摘要：

Novel porphyrin derivatives with twelve flexible alkyl chains, namely meso-tetra[4-(3,4,5-n-trialkoxybenzoylamino) phenyl] porphyrins (1a, n=12; 1b, n=16) and the zinc complex (2a) were synthesized. The mesomorphic properties were investigated by DSC, WAXD and polarizing optical microscopy; the results showed that 1a and 2a exhibit a pseudo-hexagonal columnar phase, and 1b a rectangular (Col) phase over a wide temperature range including room temperature.
