Molecular structure and surface modification of monolayer organic films

Surface functionalization and its potential application in different fields of science and technology make monolayer organic films attractive candidates as linkages between an underlying substrate and other molecular species. By now, self-assembled monolayers (SAMs) [1,2] generated from either alkanethiols (RSH) or disulfides (RSSR) (R= CnH2n+1), have become a practical tool for homogeneous surface modification. Functionalization due to a characteristic surface energy can be tailored by choosing the desired specificity of the exposed end groups.
