Outline of Final Research Achievements

Porphyrinoids have collected recent attention as pi-conjugated electronic materials with the dawn of molecular electronics. Their ultimate goal lies in fabricating single porphyrinic wires and sheets, which are used as molecular wiring and semiconducting materials. However, porphyrinic wires and sheets are still too short and small for the purpose. Herein, the author aim at fabricating pi-conjugated azaporphyrin wires and sheets by means of novel processes. During the research period, the author established fabrication procedures for dipyrrin nanowires and nanosheets, which are the basic substances for this research. The dipyrrin nanowires and nanosheets also show photofunctionalities.
