Figure 3. (A) High-resolution TEM images and (B) corresponding FFT patterns of a C₂₄H₂₄FeNP nanocluster on a GO nanosheet; (C) High-resolution TEM images and (D) corresponding FFT patterns of an AFc nanocluster on a GO nanosheet; The main spots of the FFT patterns correspond to the lateral molecular arrangement of Fe ions in the molecules shown schematically in (E) the C₂₄H₂₄FeNP and (F) the AFc nanocluster; (G) The fundamental unit of the lateral arrangement is formed three-dimensionally by the corresponding Fe ions (orange and blue dots). TEM: Transmission electron microscope; FFT: fast Fourier transform; GO: graphene oxide; AFc: amino-ferrocene.
