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 sur...

The electron impact induced fragmentations of some hexaalkyl disiloxanes have been studied with respect to the effect of the size and the positions of different alkyl substituents at the Siatoms. Positional isomers of hexaalkyl disiloxanes differing by the distribution of alkyl groups over both Si-atoms can be easily distinguished by large intensity differences of fragment ions in the 70eV EI-m...
