Complex compounds of various types and nature have been widely applied in many fields of science and technology. Complex aggregates based on nanostructures such as nanotubes and other coordination compounds, for example, metallocenes, have unique properties, since a combination of their individual characteristics provides for further growing interest to the research in chemistry, physics, electronics, medicine, etc.  
        Unique physical properties of multi-walled nanosystems (especially of grapheme/silicene-based ones) have been the subject of keen interest lately. Their specific energy-band structure with a zero band gap and linear dependency of electron and hole energy spectrum from the wave-vector cause the electric charges to behave like relativist particles with zero effective mass. Anomalous transportation and field effects open a wide prospect of their applying in nanoelectronics. Such nanostructures are assumed to be promising spintronics materials due to the long electron free path, weak spin-orbital interaction and the long spin scattering. What is more, the chemical or physical modification of multi-walled nanosystems enables to reveal their new extraordinary features. Thus, intercalation with atoms (molecules) allows to change the Fermi level position, relative electron and hole concentration, without considerable changes in energy-band structure of source nanomaterials.
        On the other hand, unique optical, electrical and magnetic, and also biological behaviour of “guest” component stimulate creation on their base of intercalates with multi-walled systems (“huest” component), since the ability of these complexes to coordinate with multi-walled systems allows to obtain new materials as effective elements for photo- and magnetosensitive devices, drug delivery, imaging and therapy, as well to use these materials as an antidetonant in motor and aviation fuels.

Future Projects and Goals
