Abstract

Diazaporphyrin-C₆₀ linked dyad has been prepared to assess intrinsic electron transfer properties of diazaporphyrins for the first time. The dyad exhibited the efficient formation of a charge-separated state which has a lifetime 4× longer than that of the corresponding porphyrin-C ₆₀ linked dyad with the same spacer. In accordance with this elongation, a SnO₂ nanostructured electrode modified with the diazaporphyrin-C₆₀ dyad also revealed enhanced photocurrent generation in the visible region in comparison with that with the porphyrin-C₆₀ dyad. These results show that diazaporphyrins are highly promising building blocks for the construction of artificial photosynthesis and solar energy conversion.
