Abstract:
The present article describes the synthesis of hybrid composite film materials formed during the self-assembly process through non-covalent interactions of graphene oxide (GO) nanosheets with salt 1, represented by an anionic spin-crossover complex [Fe III (5Cl-thsa) 2 ] − (5Cl-thsa – 5-chlorosalicylaldehyde thiosemicarbazone) and the organic tetraethylammonium cation [Et 4 N] + . The insertion of the salt 1 molecules into the interlayer space of GO nanosheets with the subsequent formation of a hybrid material GO–1 was observed. The film of the hybrid material GO–1 was characterized by scanning electron and confocal laser microscopy, EDX and XPS analysis, IR, Raman and 57 Fe Mössbauer spectroscopy, dc magnetic measurements, and powder X-ray diffraction. Comparison of the magnetic properties of salt 1 and a film of the hybrid material GO–1 demonstrated a significant influence of the GO nanosheets matrix on the completeness of spin transition and showed a slight shift of the hysteresis loop by 1 K in the temperature range of 200–230 K. DFT calculations showed an important role of the organic cation [Et 4 N] + in the process of adsorption of the spin-crossover anion [Fe III (5Cl-thsa) 2 ] − on the GO nanosheet surface.
