The stability ofmolecular surfacelayers can be enhanced by the formation of bonds between the individual molecular units. In self-assembled monolayers of biphenylthiols and other aromatic thiols, such cross-linking can be achieved byelectron irradiation.9,28Following electron-induced dissociation of CH ...
