Outline Activities
He has found a novel porphyrin isomer, N-confused porphyrin (NCP) and opened a new avenue to novel porphyrinoids.(J. Am. Chem. Soc., 1994)
A variety of NCP metal complexes, multiply confused, expanded, and contracted porphyrinoids, have been synthesized and characterized by the X ray single crystal analyses. (Chem. Commun. 2002) Especially, the multiply confused porphyrins have been shown to exhibit a self-assembly property for moleculer wires. (Supramol. Chem. 2003)
With the assist of "confusion approach" strategy,new synthetic method for porphyrinoids has been developed.
He has succeeded to synthesize doubly N-confused hexaphyrins that possessed two N3C compartments for the complexation of two metal ions in the cavity.

Research Interests
  • (3) Functional Organization of Porphyrin Analogs
    keyword : Porphyrin, Pyrrole, Self-Organization
    2002.10Assemble molecules using the intermoleculer interactions show the special properties differnt from each molecule such as an artificial bilayer. Doubly confused porphyrins performs a one-dimensional chain in the solid state by the hydrogen bonds between outer N atoms. It is clear that a porphyrin forms an orderly structure assembly by the result of STM study. Our porphyrin derivateves, NCPs, may also use as a photosensitizer for a memory or as an ion transporter in the biomembrane..
  • (2) Creation of Novel Porphyrin Analogs - Multiply Confused, Expanded
    N-Confused Porphyrin

    keyword : Porphyrin, Pyrrole,confused porphyrin
    2002.10Doubly confused porphyrin and dubly confused hexaphyrins which have two confused pyrroles in the ring stabilize thire high ox-dation state of metals and constract binuclear metal compleaes. Further more, the study of the photodynamic therapy using their property which has a good generation efficiency of singlet oxygen has been started..

    Metal Coordination Chemistry associated with NH-Tautomerism
    keyword : Porphyrin, Pyrrole, Tautomerism, Macrocyclic Compound
    2002.10The NCP has NH tautomers due to transfer protons between inside and outside nitrogen atoms, and each tautomer has different UV/vis absorbance (the color change) and aromatisity. Thus, there are two types of tautomers, one is three hydrogen atoms in the core (NCP-3H), another is two hydrogen atoms in the core (NCP-2H). In nonpolar solvents NCP-3H exists predominant, and in the polar solvent NCP-2H is more stable. Each NH tautomer's structures have been determined by X-ray diffraction analysis. (JACS 2001) The control of tautomerism will be possible to introduce the substances at aloha position in the outside ring..
