Abstract
A method for preparation of homogeneous samples of metal-phthalocyanines doped with alkaline metals was developed. Polycrystalline samples of zinc phthalocyanines doped with sodium, potassium, and rubidium atoms were investigated. We measured the temperature dependence of ESR spectra of prepared samples and studied their composition and structure. It is shown that their magnetic properties depend strongly on the degree of doping as well as on the subsequent grinding and annealing.
