Collisions of C6H6(+.), C6D6(+.), C6H5F(+.), C60(+.), and C60(++) at Fluorinated and Non-Fluorinated Self-Assembled Monolayer Films
Abstract
Mass spectra obtained by colliding singly-charged benzene, benzene, benzene-d and fluorobenzene and singly- and doubly-charged buckminsterfullerene with self-assembled monolayer films are reported These surfaces were prepared by the spontaneous assembly of C2 C3, C4, C10, and C18, n-hydrocarbon thiols, perdeuteroeicosanethiol and 2-(perfluorooctyl)-ethanethiol on both gold foil and vapor-deposited gold are reported and discussed. The fluorinated surface provides the highest internal energy deposition; more extensive fragmentation of doubly-charged buckminsterfullerene could be observed on the other surfaces. Chemical reactions, such as H and CH3 additions, as well as the analogue F and CF3 additions, between benzene and fluorobenzene molecular ions and-the monolayer films have been proved. These processes, ab initio 6-31G //6-31G SCF total energies and experimental heats of formation were used for the characterization of the surface-projectile interactions.
