首次成功地合成了[8]-和[10]环对苯乙烯（CPPs）。[8]-环对苯炔和[10]环对苯炔在晶体状态下组织成人字形几何形状，分别具有1.1和1.4 nm的明确的圆柱形空腔。在大量材料可用的情况下，通过x射线衍射分析验证了固态[10]CPP与C-60之间的高效凹凸pi-pi相互作用。
A cost-effective gram-scale synthesis of [8]- and [10]cycloparaphenylenes (CPPs) has been developed for the first time. Both [8]- and [10]cycloparaphenylene organized into herringbone geometries in the crystalline state with well-defined cylindrical cavities of 1.1 and 1.4 nm, respectively. With large amounts of material available, the highly efficient convex-concave pi-pi interactions between [10]CPP and C-60 in the solid-state was validated by X-ray diffraction analysis.
