The synthesis of expanded porphyrins has been intensively explored for the last three decades. Expanded porphyrins1 exhibit various physical properties and reactivities that are entirely different from those of simple porphyrins. In 1996, Smith and coworkers reported2,3 the first preparation of a porphyrin system in which the macrocycles were covalently fused at their b-pyrrolic positions. Because of their unique properties, they are of increasing interest to the scientific community. On the other hand, the importance of aggregation in the field of coordination chemistry has been recognized from studies on the chlorophylls in nature.4 A synthetic model LH antenna without the protein matrices challenging from viewpoint of synthetic accessibility to nature’s methodology. For example, Kobuke5 reported a complementary coordination of bis(zincimidazolylporphyrin) to construct a macrocyclic porphyrin array to mimic the chlorophyll dimer in LH2. This study focused on heterodyads, in which a porphyrin was fused with an other chromophore moiety through the p-aromatic systems of the two molecules by the sharing of two adjacent b-carbons. We aimed at modifing the pyrrole-fused-porphyrin, which is used to model the self-assembly characteristics of chlorophyll. We reported a simple approach for the construction of self-organizing structures via ligand-to-metal coordination. X-ray intensity data of 12090 reflections (of which 9067 are unique) were collected at 150 K on a Bruker CCD X-ray diffractometer (Apex II Ultra CCD System) using a graphitemonochromated Mo Ka (l = 0.71073 Å) radiation source.
