Self-assembled multilayer films of fullerene-diaminododecane on (MeO)Si(CH3)2(CH2)4NH2-modified oxide surfaces

The multilayer film of self-assembled fullerene-diaminododecane (DAD) were prepared on 4-aminobutyldimethylmethoxysilane (ABS)-modified planar Si oxide, quartz and nonplanar fumed silica (Cab-O-Sil) surfaces by a novel approach. FTIR, UV, and ellipsometry was used to characterize the formed films. The film growth was observed indirectly by several data, but the structure of C60-DAD multilayer films is not clearly determined yet. The formation of the C60-DAD layer on ABS-modified Cab-O-Sil surface is slow and strongly depends on the packing density of initially anchored ABS-fullerene monolayer as compared planar substrate.
