We have synthesized the uracil units conjugated to a porphyrin, of which atropisomerization was regulated by steric replusion between methyl substituents at the pyrrole ß-position. The αα isomer formed a dimmer structure with two melamine derivatives as complementary units via hydrogen bonds. The NMR experiment indicated that the stable dimmer structure formed in toluene diluted solution and the αβ isomer formed an array structure in high concentration. The different structure was discussed from the view of the dioxygen binding property.
