A monolayer of C60 tethered to the surface of an inorganic substrate : assembly and structure

We have devised a novel approach to tether the fullerene C[sub 60] to silicon surfaces via a (pyridyl)[sub n]-OsO[sub 4]-C[sub 60] coordination complex employing a pyridyl-terminated, self-assembled monolayer chemisorbed to the substrate. The structure of the (pyridyl)[sub n]-OsO[sub 4]-C[sub 60] monolayer complex tethered to the SiO[sub x] surface of the substrate, is fully consistent with both the profile and in-plane structures determined by high-resolution X-ray crystallography. While the profile structure has been derived by X-ray interferometry and proven to be unique by X-ray holography, the in-plane /out-of-plane structure is simply a model consistent with the six stronger reflections in the relevant I(Q[sub xy],Q[sub z]) diffraction data. 6 refs., 3 figs.
