| Outline of Final Research Achievements |
In this study, we have mainly studied on the molecular design and physical properties of two novel pi-electron systems with peculiar electron structures. (1) Pyrrole-fused azacoronenes with directly attached carbonyl groups were newly synthesized and they showed characteristic NIR absorption in the spectra. Combined with other measurements and calculations, it is suggested that new pi-systems had stable open-shell character in their neutral states. (2) pi-electron donor and acceptor segregated pi-conjugated oligomers were synthesized with naphthobipyrrole as a donor and fluorobenzene as an acceptor. In the lower temperature the segregated structures became clearly.
