概要

• 論文の詳細を見る

• Recently, a conductive coordination compound [Cu(TANC)](F)_<0.5> with new radical frameworks was synthesized, where TANC stands for 5, 6, 11, 12-tetraazanaphacene. We have measured the electrical resistivity of [Cu(TANC)](F)_<0.5> under high pressures up to 8.0 GPa. At ambient pressure, the temperature dependence of the resistivity shows semiconducting behavior described by a variable range hopping conduction, ρ(T)〜exp(T_0/T)^η. The value of T_0 increases with increasing pressure up to 6.5GPa, beyond which it decreases abruptly. The pressure dependence of T_0 is discussed in terms of the increase of the pureness of one-dimensionality and the strength of the random potential due to disordered F^- ions.
