Outline of Final Research Achievements

Yamamoto: Using a newly prepared tridentate ligand, new hypervalent sulfur and selenium radicals could be isolated and characterized. The corresponding sulfur anion bearing Li+ was used as cathode-active materials together with a silyl radical species which was developed by Sekiguchi as the anode. A series of pentacoordinated nitrogen radical cations by using of newly prepared trident ate ligands could be synthesized and the dimer showed greatly enhanced two-photon absorption (TPA) properties.
Nakano: Nakano et al. theoretically investigated the electronic states and optical properties of Chichibabin's hydrocarbon derivatives including N atoms synthesized by Yamamoto et al. based on the open-shell character. Nakano et al. also succeeded in clarifying the correlation between open-shell character and nonlinear optical properties of Si/Gi-substituted benzenes and four-membered ring compounds including heavy main group elements in collaboration with Sekiguchi et al. (A02 group).
