| Outline of Final Research Achievements |
A Ni(II) complex of porphyrin meso-oxy radical was synthesized. This complex exhibited ferromagnetic interaction in the solid-state upon pyridine coordination via spin-crossover. A series of phenylene-linked porphyrin meso-oxy-radical dimers and trimers were prepared and the magnetic behavior was investigated.
To gain insights about the stability of porphyrinoid-based radicals, we synthesized stable subporphyrin aminyl radical, porphyrin aminyl radical, triaminyl triradical, helicene-embedded porphyrin radical, and radical cation of figure-of-eight shaped [37]octaphyrin. In addition, we synthesized a stable nitrenium ion through one-electron oxidation of the porphyrin aminyl radical.
