Charged nanobelts: The radical cation and the dication of [8]cycloparaphenylene ([8]CPP) were prepared and isolated as hexahaloantimonate salts by the one- or two-electron chemical oxidation of [8]CPP with NOSbF6 or SbCl5 . ESR spectroscopy of CPP(.+) and single-crystal X-ray analysis of CPP(2+) demonstrated that the spin and charge were equally and fully delocalized over the para-phenylene rings.

[8]环对苯撑（[8]CPP）的自由基阳离子和二阳离子通过 NOSbF6 或 SbCl5 对[8]CPP 的一或二电子化学氧化制备并作为六卤代锑酸盐分离出来。CPP(+)的 ESR 光谱和 CPP(2+)的单晶 X 射线分析表明，自旋和电荷在对位苯环上完全离域。
