Self-assembled porphyrins have attracted an attention because of their potential use of new function materials. We have synthesized the uracil units conjugated to a porphyrin, of which atropisomerization was regulated by steric replusion between methyl substituents at the pyrrole β-position. The 2D-DOSY experiment indicated that the αα isomer formed a dimer structure with two melamine derivatives as complementary units via hydrogen bonds and the αβ isomer formed a zig-zag structure in high concentration. In addition, the porphyrin which bears barbituric acid as 2DAD type was designed and synthesized, and the possibility of the construction of polymeric porphyrins was discussed in solution and solid phases.
