Creation and It's Functionality of Silylated Fullerenes

自从C60的分离得到了大量的应用以来，人们一直在关注这种新的同素异形体形式的碳的化学官能化，并不断产生令人着迷的结果。迄今为止，外消旋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功能。富勒烯与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，我们进行了富勒烯和内嵌金属富勒烯与乙硅烷衍生物的反应，它不仅可以作为一个有吸引力的合成试剂，而且也是一个机制探针，以澄清富勒烯和内嵌金属富勒烯的化学和电子性质。在本研究项目中，我们发现了以下新型的富勒烯和内嵌金属富勒烯与有机硅化合物的光化学双硅烷化反应，以提供相应的新型富勒烯基有机硅材料和新型的不饱和化合物通过电子转移过程的双硅烷化反应，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.
