抄録

Phthalocyanine conductor NiPc (As₆) _{0. 5} is a double-chain system: a metal chain and macrocyle chain coexist within the same molecular column. This characteristic structure produces a two-band system: a wide π-band and narrow d-band, which is located near the Fermi level of the wide π-band. In this system, high pressure tunes the energy level of this 3d_z²-band, and induces a metal-ligand charge transfer from the 3d_z²-band to π-band, which was verified by the absorption spectra of infrared, near-infrared, and visible region. The vacant state of the 3/4-filled π-band is continuously filled up to 7 GPa. According to the increase of the pressure non-metallic phase which exists below 40 K at ambient pressure evolves to almost room temperature around 1 GPa.
