Outline of Final Research Achievements

Molecular photonic wires, MPWs, are one of the most basic but important components in molecular photonics. They take on transmission of photonic information among various components such as a logic gate. In this project, the author aimed at the realization of MPWs based on bis(dipyrrinato)zinc(II) complexes with intense absorption and fluorescence. Herein, the author has found that asymmetric dinuclear complexes undergo quantitative excition transfer from one end to the other. This result is very important because it shows possibility of realizing efficient MPWs upon elongation of the dinuclear complex. The author has also fabricated one-dimensional nanowires and two-dimensional nanosheet showing photoelectric conversion ability.
