C_(60)/C_(70)(英文名 Fulleren,其中文可称球碳(烯)或富勒碳)。是本世纪九十年代在化学领域中的一个最重大的发现。球碳及其 n—掺杂衍生物在电子学、光电导性和磁学上都显示了一系列奇异的性能。如能将这类球碳的优异性能与高分子材料结合起来,将会开创出一类具有挑战性的新材料。最近的文献报道指出有两种结合方式,其一是将 C_(60)/C_(70)分子挂在大分子链的一侧,称为“on—chain”的“Fulleroplastic”(球碳塑性体);其二是使球碳成为高聚物主链的一种结构单元,称为“in—chain”的“Polyfullerene”(球碳高聚物)。从性能上讲,前者优于后者。
C_ (60) / C_ (70) (English name Fulleren, the Chinese can be called spherical carbon (olefin) or fullerene). Is one of the most significant discoveries in chemistry in the 1990s. Ball carbon and its n-doped derivatives show a series of singular properties in electronics, photoconductivity and magnetism. The combination of the excellent properties of these ball carbons with polymer materials will create a new class of challenging new materials. Recent literature has reported that there are two ways to combine, one is to hang the C60 / C70 molecule on one side of the macromolecule chain, the “Fulleroplastic” called “on-chain” ); The second is the “fullerene” (ball carbon polymer) called “in-chain” which makes the spherical carbon a structural unit of the polymer backbone. In terms of performance, the former is superior to the latter.
