The dopant is an electron acceptor and the cage is a donor which is different from the case of metallofullerenes.

在这种包合物中有机小分子是电子的受体，而碳笼则为电子的给体，这与金属富勒烯包合物恰恰相反。

For every dopant has its advantages and disadvantages, results of recent studies show that double-donor doping and donor-acceptor codoping can improve the performance of the material remarkably.

由于各掺杂物的优缺点不同，近几年研究发现，双施主掺杂和施受主共掺能够很好的改善材料的性能。
