Abstract

The macrocyclic donor, D = 1,4,5,8,9,12,13,16-octamethyltetrabenzporphinato nickel (II), forms two mixed-valence complexes D^+γ (I^-₃)_γ, with γ = 0.36 and 0.97, that combine high electric conductivity σ(T) with a nearly Curie-law magnetic susceptibility. These molecular conductors are the first clear realizations of the partly-filled (γ < 1) atomic limit of the Hubbard models, when the bandwidth 4|t| is small compared to on-site correlations U. Single crystal epr and σ(T) data on γ = 0.36 crystals are interpreted as correlated motion of localized D⁺ polarons on a one-dimensional ...D^+γD^+γ... stack.
