Microwave Dielectric Constant and Conductivity Measurements in the Phthalocyanines

Dielectric constant and loss measurements have been made on α, β, and X metal free and copper phthalocyanine at microwave frequencies. Measurements were carried out on pressed pellets of polycrystalline material. Dielectric constant data is analyzed in terms of a powder dielectric model. The relative dielectric conductivities of these phthalocyanines are examined along with similar measurements on various β transition metal phthalocyanines. Dielectric conductivities of these metal phthalocyanines appear to be consistent with dc conductivities reported in the literature.
