The first cycloparaphenylene (CPP)-based ionic donor-acceptor supramolecule Li(+)@C60⊂[10]CPP⋅X(-) has been synthesized. X-ray crystallography not only confirmed the molecular structure of Li(+)@C60⊂[10]CPP⋅X(-) but also uncovered the formation of a unique ionic crystal. The strong charge-transfer interaction between [10]CPP and Li(+)@C60, which was confirmed by electrochemical measurement and spectroscopic analyses, caused significant delocalization of the positive charge across the entire complex.
首个基于环对苯撑（CPP）的离子给体-受体超分子 Li(+)@C60⊂[10]CPP⋅X(-) 已被合成。X 射线晶体学不仅证实了 Li(+)@C60⊂[10]CPP⋅X(-) 的分子结构，还揭示了一种独特的离子晶体的形成。电化学测量和光谱分析证实了[10]CPP 和 Li(+)@C60 之间的强电荷转移相互作用，导致整个复合物的正电荷发生显著离域。
