Ziolkovskiy D. Anion-radical salts of tetracyanoquinodimethane with pyrazine derivatives based cations

Investigation objects: anion-radical salts (ARS) of tetracyanoquinodimethane (TCNQ) with pyrazine and its derivatives based cations. Purpose: to reveal peculiarities of the influence of quantity, space arrangement and type of substituents in the pyrazine-based cations on the crystal structure, optical, electrophysical and magnetic properties of the ARS TCNQ on its base. Determination the ability of increasing dimensionality of their properties. Methods: spectroscopy in VIS and IR range, raman and IR reflectance measurements. X-ray analysis, temperature dependence of electrical resistance, magnetic susceptibility and heat capacity. Studied the influence of cation structure and composition on the optical, electrophysical and magnetic properties of the ARS TCNQ. It is shown, that some of the synthesized compounds has the increased properties dimensionality. Degree of application: increased dimensionality of properties and peculiarities of magnetic ordering of the synthesized compounds gives the abilityto use these ARS as materials in sensors and microelectronic.
