Kinky catalysis : Surface defects, such as step edges and kinks, are thought to be the ‘active sites’ that induce site‐specific chemical reactions on catalytic materials. The catalytic dissociation of a bromine atom from an organic molecule is shown to occur at kink sites on the stepped Au(10,7,7) surface (see scheme; Br=red). The anisotropic surface also facilitates the production of highly aligned polymers, formed by on‐surface covalent coupling of monomer units.
