Synthesis and characterization of sulfur derivatives for self assembly of monolayers of fullerenes at gold surfaces

The chemical reactivity of C$\sb{60}$ makes it an ideal candidate for the addition of derivatives and sidechains. Early derivatives involved the addition of metals such as osmium, ruthenium, and platinum. C$\sb{60}$ was soon found to hydrogenate via Birch reduction, halogenate, react with free radicals, and undergo cycloaddition with diazomethanes. This last addition process is of particular importance, because all other reactions add to the cage by breaking double bonds, thereby disturbing the total conjugation of the system. The bridging mechanism of the cycloaddition system preserves this conjugation which may be valuable for studies involving electron transfer. / Thiols, disulfides, and dialkyl sulfides have all been demonstrated to chemsorb to clean surfaces of gold, silver, copper, and platinum. Functionalized molecules containing these groups, may be studied at surfaces as true monolayers, as an alternative to films formed by the Langmuir-Blodgett technique. / The diazo cycloaddition of a sulfur derivative to C$\sb{60}$ may provide the first true monolayer of an undisturbed fullerene, and a more thorough insight into the electronic behavior of this interesting molecule. / This work discusses the purification processes of the fullerene and the synthetic route to the preparation of these derivatives. / Source: Dissertation Abstracts International, Volume: 56-08, Section: B, page: 4288. / Major Professor: Joseph B.
