摘要：

A new ''picket-fence'' porphyrin precursor with carboxy terminal groups has been prepared. Four atropisomers of meso-tetra(o-methoxycarbonylphenyl)porphyrin have been separated by chromatography. The conformational stability of the alpha-alpha-alpha-alpha-isomer was examined to the prolonged heating for both free base and zinc complex. The usefulness of meso-tetra(o-carbonylphenyl)porphyrin appeared to be not at all inferior to well-known meso-tetra(o-aminophenyl)porphyrin.
