電気伝導 Newly Developed Metallic Molecular Crystals
Molecular crystals had been long cosidered to be electrically unattractive materials. But this old image was renewed dramatically by the appearance of the recently developed π-molecular metals and superconductors. The Fermi surfaces calculated by the simple extended-Hü ckel tight-binding band calculations have been confirmed by the oscillatory magnetoresistances and magnetic susceptibilities in some organic metals and molecular conductors based on transition metal complex molecules. Several typical molecular conducting systems, which played crucial roles in the development of the new frontier of molecular conducting systems, are described with putting a special stress on the structure chemical aspects. New types of molecular metals with π-metal electons interacting with magnetic ions are also mentioned briefly.
