The morphology of multilayer GO was confirmed from
transmission electron microscopy (TEM) image (Fig. 6). The GO
surface with relatively thick, randomly stacked aggregates and
crumped sheets loosely stack together was observed.
However, the SAED from the GO shows ring pattern with a
closed bright spots, unlike the symmetric hexagonal lattice
with an average d-spacing of about 0.71 nm. The plausible
mechanism for the oxidative coupling of 2-naphthol to BINOL
is shown in the Scheme S2 (supporting information).25,29
