多面体分子因其引人注目的结构和独特的化学而吸引人。这样的全氟化,通常会产生很大的应变,是一个重大挑战。它极大地改变了电子分布,结构和属性。值得注意的是,小型高对称性全氟多面体的特征是位于中央,星形低能未占据的分子轨道,可以在多面体框架内承载一个额外的电子,从而产生自由基阴离子,不失去对称性。这种预测的电子托管能力肯定是为全氟卡布确定的,第一个被分离纯的全氟化柏拉图式多面体。承载原子,这种“笼子”结构中的分子或离子是,然而,除了直率,当不是虚幻的时候,提供不容易获得超分子结构。虽然金刚烷和古巴在材料科学中促进了许多应用,医学和生物学,其全氟对应物的具体用途仍有待确定。高氟化碳同素异形体的某些方面,如富勒烯或石墨,简要提及上下文。
Polyhedral molecules are appealing for their eye-catching architecture and distinctive chemistry.
Perfluorination of such, often greatly strained, compounds is a momentous challenge. It drastically changes the electron distribution, structure and properties. Notably, small high-symmetry perfluoropolyhedranes feature a centrally located, star-shaped low-energy unoccupied molecular orbital that can host an extra electron within the polyhedral frame, thus producing a radical anion, without loss of symmetry. This predicted electron-hosting capacity was definitively established for perfluorocubane, the first perfluorinated Platonic polyhedrane to be isolated pure. Hosting atoms, molecules, or ions in such \"cage\" structures is, however, all but forthright, if not illusionary, offering no easy access to supramolecular constructs. While adamantane and cubane have fostered numerous applications in materials science, medicine, and biology, specific uses for their perfluorinated counterparts remain to be established. Some aspects of highly fluorinated carbon allotropes, such as fullerenes and graphite, are briefly mentioned for context.
