Outline of Final Research Achievements

1) Synthesis and Function of Radical-Metalloids: Nitronyl nitroxide-2-ide (NN-2-ide) anion can coordinate on groups 10 and 11 metal ions. These radical metalloids have characteristic feature of low oxidation potential for the NN-moiety. Of these, NN-Au(I)-phosphine complexes are readily prepared and applicable to the Pd(0)-mediated cross-coupling reagent as a NN source. Furthermore, we synthesized a trimer of iminonitroxide (IN)-Au(I), [(IN)-Au(I)]3, in which the three IN radicals ferromagnetically interact in an intramolecular fashion.
2) Photochemically Induced Long Lived Charge Separation States Using Spin-Orbid Coupling of Pt(II) in Donor-Pt-Acceptor Complexes: Photoinduced charge separation in dianisylphenylamine-Pt(II)-naphthalenediimide (D-Pt-NI) triad was investigated. Irradiation of a THF solution of the triad produced the charge separated state with a lifetime of 4.3 microsecond under zero-magnetic field (B = 0 mT) and 9.6 microsecond under B = 270 mT.
