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.

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脱气石英管中在20℃的光照射。用低压汞弧灯制备了C60/聚硅烷加合物，产率中等，其中C60并入聚硅烷单元。还阐明了该加合物的独特电子性质。自1985年发现C60的特殊稳定性后首次提出以来，将一个或多个金属原子封装在空心富勒烯笼内（内嵌金属富勒烯）一直引起人们的特别关注，因为它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。这表明内源性金属富勒烯既可以作为强电子供体，也可以作为强电子受体。研究了内源性金属富勒烯可以作为聚硅烷的掺杂剂。
