Figure 9. (A) A common strategy for the functionalization of 2D (inorganic) materials, consisting of two steps. (B) Pre-synthetic functionalization, where the functionalized block is first obtained prior to mechanical stripping, resulting in a quasi-perfect array of unaltered functional groups attached to the surface. (C) (i) Low magnification TEM image of a thin section, where the darker grey areas are associated with thicker sections; (ii-iv) The experimental SAED pattern corresponding to the [0 0 1] area axis (iii) was obtained for the selected area [surrounded by the green circle on the TEM image in (ii)] and fitted very well with the simulated SAED pattern (iv).
