The electronic properties of porphyrin zinc aggregates wired using single‐walled carbon nanotubes (SWNTs) are described. A self‐assembled structure is formed by casting a solution of SWNTs and 5,15‐bispentylporphyrinato zinc( II ) (BPP‐Zn) onto a substrate (see figure). Rectifying behavior has been observed at SWNT/BPP‐Zn junctions, although no rectification is seen for bare SWNTs. The results show that aggregates of even a few BPP‐Zn molecules work as a rectifying device with SWNT wiring.
