Addition of Hydroxide and Alkoxides

The CgQ surface coverage was determined to be 2.0 10 mol cm . The monolayer can be further modified with monomeric amine reagents, which demonstrates the potential of the self-assembly process for growing three-dimensional fullerene structures. Different surfaces such as quartz. Si-oxide [105] or ITO [102] were coated with multilayers of fullerene up to stacks of 9 layers. An imidirectional electron transfer is possible across the fullerene mulhlayers [102]. Not only can multiple layers of fullerenes be connected to a certain surface but amino-functionalized can also serve as a linker between two different surfaces. 3-Aminopropyl-tethered glass plates could be linked via a Cgg layer to 3-aminopropyl covered zeolite crystals [106]. 

The first step in the addition of alkoxides to Cgg is, consistently, the formation of the alkoxy Cgg anion. The subsequent process is strongly dependent on the presence of oxygen. In the presence of oxygen, 1,3-dioxolane derivatives of Cgg are formed [110]. In the absence of oxygen the oligo alkoxy fullerenide anions can be formed [111, 112]. Reaction of alkoxides with Cgg usually results in complex mixtures. This may be why only a few reactions of Cgg with alkoxides have been described [113]. Nevertheless, defined alkoxy fullerenes can be obtained by nucleophilic substitution reactions of alkoxides with halogenofullerenes (Chapter 9) [113].
