摘要：

We have found that nonlinear current voltage characteristics (I-V curves) are observed in the Mn-12 {[Mn12O12(O2CC6H5)(12)(O2CC6H4NH2)(4)(H2O)(4)]center dot 2(CH2Cl2)} molecular redox array in the temperature range from 10 to 300 K. Among them, I-V characteristics with threshold voltages (V-th) are clearly observed from 10 to 80 K. The I-V curves with V-th can be well fitted by applying the one-dimensional (1D) Coulomb blockade (CB) model. The V-th value is 280 mV at 10 K and decreases linearly with increasing temperature. These results indicate that each Mn-12 acts as a CB element in the ID array at 80 K or below. Thus, it is suggested that the Mn-12 molecular redox system can be described by the CB behavior.
