Abstract
The solid-solid chemical reactions of phenols or ketones, such as β-naphthol (1) or anthron (2), with FeCl3⋅6H2O by ultraviolet irradiation give coupling dimeric products. The mechanisms are studied using atomic force microscopy (AFM) and known crystal packing data. AFM reveals that the crystal face (100) of 2 or (001) of 1 exhibits stumpy protrusions all over the surface from the contact edge of the crystals, respectively, whereas the long side face (010) of 2 gives volcanoes. All of those are guided by the crystal structure. Molecular interpretations of the AFM features are given.
