Abstract

Recent progress in fundamental studies on multiporphyrin arrays has provided structural parameters for the molecular design of artificial light‐harvesting antennae which mimic the wheel‐like antenna complexes of photosynthetic purple bacteria. Covalent and noncovalent approaches have been employed for the construction of artificial light‐harvesting multiporphyrin arrays. Such arrays are categorized into ring‐shaped, windmill‐shaped, star‐shaped, and dendritic architectures. In particular, dendritic multiporphyrin arrays have been proven to be promising candidates for both providing a large absorption cross‐section and enabling the vectorial transfer of energy over a long distance to a designated point. Such molecular and supramolecular systems are also expected to be potent components for molecular electronics and photonic devices.
