通过用锂金属（R5C605-/Cor(4-)/9Li(+)）还原衍生的富勒烯 Me5C60H 和 Ph5C60H 以及 Corannulene，制备了前所未有的高度还原测地 pi 系统超分子堆叠。主客体组装体的形成是由于锂阳离子和阴离子部分之间增强的静电相互作用，以及弯曲碳氢化合物之间的结构相容性。这些新的超分子组装体（异二聚体）的高稳定性使得能够在系统中引入另一种组织基序。这是通过使用束缚的Corannules作为主体分子来实现的，这导致形成束缚的双异二聚体((Me5C605-/Cor(4-))(2)(CH2)(8)/18Li(+))。
Unprecedented supramolecular stacks of highly reduced geodesic pi-systems were prepared by the reduction of the derivatized fullerenes Me5C60H and Ph5C60H and corannulene with lithium metal (R5C605-/Cor(4-)/9Li(+)). The host-guest assemblies form because of the enhanced electrostatic interactions between the lithium cations and the anionic moieties, in addition to the structural compatibility between the curved hydrocarbons. The high stability of these new supramolecular assemblies (heterodimers) enables the introduction of another organization motif to the system. This is achieved by using tethered corannulenes as host molecules, which leads to the formation of tethered bis-heterodimers ((Me5C605-/Cor(4-))(2)(CH2)(8)/18Li(+)).
