Paper Abstract

A mesomorphic long-chain tetraphenylporphyrin was investigated on the visible absorption and fluorescence spectra and the fluorescence lifetime was measured through the phase transitions. All results indicate that the low- temperature lamellar mesophase has face-to-face molecular arrangement, through the high-temperature one does not as the proposed structures based on the powder x-ray diffraction studies.
