Temperature dependence for the frequency position of the low-frequency dielectric dispersion in the polyacenequinone spectrum and quantum measurements

Abstract

The current state of the art in the physics of mesoscopic and strongly correlated electron systems [1] necessitates an appeal to the conceptual tenets of quantum mechanics [2, 3]. We associate the low-frequency (LF) dispersion region in the dielectric spectrum of polyacenequinone (PAQ) synthesized by polycondensation of pyrene with pyromellitic dianhydride at 300 ° C with the phenomenon of quantum coherence in a system of donor‐acceptor (D‐A) complexes. We imply a system of atmospheric oxygen intercalated into graphite-like fragments of the surface-layer structure of PAQ granules and two-dimensional polyaromatic layers [4]. In the present paper, the temperature behavior of the LF maximum in the frequency dependence of the tangent δ ( ν ) of the dielectric-loss angle δ ( ν ) is interpreted on the basis of a scheme of quantum measurements that was recently proposed [3]. For definiteness, we assume that the intercalated oxygen interacts with the π -conjugate system of only one of the adjacent polyaromatic layers. The problem of possible elementary mechanisms of the relaxation polarization is beyond the scope of the present discussion. In the temperature dependence of the position ν m LF
