The results of research performance of porous silica matrix MCM-41 with encapsulated in the pores of β-cyclodextrin (β-CD) in cavitand and cavitant (with FeSO4) state were presented. The character of changes in the frequency dispersion of the impedance, electrical loss tangent and dielectric constant of the synthesized encapsulates at heating, illuminating and in a magnetic field were elucidated. According to the analysis of thermally stimulated depolarisation differences in the modification of the im purity spectrum caused by different type of guest content were analyzed. The conditions under which synthesized nanohybrids may be interesting in terms of the formation of quantum battery of ele ctric energy and capacitance heads for reading data from magnetic media were finded.
