| Outline of Final Research Achievements |
Dipyrrin is a planar molecule consisting of two pyrrole rings linked by a methine linker. It is characterized by a well-developed π-electron system and strong optical absorption based on the 1π-π* transition. It functions as a univalent bidentate anionic ligand by deprotonation, and spontaneously complexes with various metal ions to form neutral complexes such as bis(dipyrrinato)metal(II) complexes. In this study, dipyrine metal complex nanowires with helical and asymmetric structures were synthesized. In the former case, we succeeded in enhancing circularly polarized luminescence. In the latter case, we achieved an extension of the photoelectric conversion wavelength, increased the luminescence quantum yield, and discovered and proposed a novel methodology for the existence and demonstration of fast exciton transfer in the wire.
