Creation and It's Functionality of Silylated Fullerenes

自从C60在制备上有用的数量被分离以来，人们对这种新的同素异形性碳的化学官能化给予了很大的关注，并不断地产生令人着迷的结果。到目前为止，面外化学衍生化已得到广泛的发展。同时，有机硅化合物作为最重要的元素间化合物之一，代表了聚硅烷等材料的独特之处。富勒烯和有机硅化合物的结合有望形成一类新的有机化合物，同时开辟材料科学的新领域。在此背景下，我们开展了富勒烯和面内金属富勒烯与二硅烷衍生物的反应，这不仅是一种有吸引力的合成试剂，而且是阐明富勒烯和面内金属富勒烯的化学和电子性质的机理探针。在本研究项目中，我们发现了富勒烯和面内金属富勒烯与有机硅化合物的光化学新的双硅化反应，从而得到了相应的富勒烯类有机硅材料和不饱和化合物的光化学双硅化反应，其中C60作为光催化剂。

Since the isolation of C60 in preparatively useful quantities, much attention has been devoted to chemical functionalization of this new allotropic form of carbon which continuously yields fascinating results. So far exohedral chemical derivatizations have been extensively developed. Meanwhile, organosilicon compounds as one of the most important inter-element compounds, represent an unique feature of materials such as polysilanes. It is expected that a combination of fullerene and organosilicon compounds forms a new class of organic compounds and at the same time opens a new field in material science. In this context, we have carried out the reaction of fullerenes and endohedral metallofullerenes with disilane derivatives which can acts not only an attractive synthetic reagent but also a mechanistic probe to clarify the chemical and electronic properties of fullerenes and endohedral metallofullerenes. In this research project, we found the following photochemical novel bis-silylation of fullerenes and endohedral metallofullerenes with organosilicon compounds to afford the corresponding new fullerene-based organosilicon materials and novel bis-silylation of unsaturated compounds via an electron transfer process, in which C60 acts as a photocatalyst.
