Creation of Fullerene/Silicon Hybrid Polymer

研究了聚硅烷和环低聚硅烷与C60的光反应。C60和聚硅烷在苯中的溶液在20℃的脱气石英管中的光照射。C在低压汞弧灯下以中等产率得到C60/聚硅烷加合物，其中C60被引入到聚硅烷单元中。还阐明了该加合物独特的电子性质。自从1985年发现C60的特殊稳定性后第一个提出以来，将一个或多个金属原子包裹在中空的富勒烯笼子(面体内金属富勒烯)中一直受到特别的关注，因为这可能导致新的球形分子具有空富勒烯意想不到的新性质。M@C82的Ip值比C60和C70的Ip值小1.2-1.6 eV。此外，M@82的Ea值比C60和C70的Ea值大0.4-0.7 eV。这些结果表明，面内金属富勒烯既可以作为较强的电子供体，也可以作为较强的电子受体。研究了面内金属富勒烯作为聚硅烷掺杂剂的可能性。

The photoreaction of polysilanes and cyclicoligosilanes with C60 has been investigated. Potoirradiation of a solution of C60 and polysilanes in benzene in a degassed quartz tube at 20 。C with a low-pressure mercury-arc lamp has afforded the C60/polysilane adduct in moderate yield, in which C60 was incorporated into polysilane unit. A unique electronic property of the adduct has also been elucidated. Since the first proposal in 1985 immediately after the discovery of the special stability of C60, encapsulation of one or more metal atoms inside hollow fullerene cages(endohedral metallofullerenes)has long attracted special attention because it could lead to new spherical molecules with novel properties unexpected for empty fullerenes. The Ip values for M@C82 are 1.2-1.6eV smaller than those for C60 and C70. In addition, the Ea values for M@82 are 0.4-0.7eV larger than those for C60 and C70. These indicate that endohedral metallofullerenes can act as stronger electron donors as well as stronger electron acceptors. We investigated that endohedral metallofullerenes could act as dopant of polysilane.
