REACTIONS OF LOW-ENERGY IONS WITH FERROCENE SELF-ASSEMBLED MONOLAYER SURFACES

Collisions of low-energy Cr(CO)n+ (n = 0, 2, 6) ions with self-assembl ed monolayer surfaces bearing covalently bound ferrocene groups result in transfer of the cyclopentadienyl ligand into the gas phase as the Cr(C5H5)+ ion. High fluences of Cr+ ions lead to deposition of Cr at t he surface and subsequent Xe+ collisions liberate the metal ion. The C r atoms deposited on the surface appear to be chemically bonded to the cyclopentadienyl rings. The implications of these results for modific ation of surfaces using ion beams are discussed.
