Schematic representation of the heterostructure assembly. (a) Formation of a NBPT SAM on a gold substrate. (b) Electron irradiation induced crosslinking and reduction of the terminal nitro groups into amino groups. (c) Formation of a free-standing JNM with the terminal N- and S-faces. (d) Functionalization of the N- and S-faces with C60 and AuNP, respectively. (e) Assembly of a (C60–JNM)n (here n = 3) hybrid heterostructure by mechanical stacking. Color code for atoms: black – carbon, grey – hydrogen, blue – nitrogen, green – sulfur, and red – oxygen.
