In this issue of Chem, Stoddart and co-workers present a strategy for preparing positively charged catenanes bearing ≤7.3 charges per cubic nanometer through a templation approach. Using Cu as both a reducing agent and catalyst, they produced an enthapically and entropically demanding 12+ charged [3]catenane and 24+ charged [5]catenane.

在本期《化学》杂志中，Stoddart及其同事提出了一种通过模板法制备每立方纳米电荷≤7.3的带正电荷的链烷的策略。使用铜作为还原剂和催化剂，他们产生了既熵又熵要求的12+带电荷的[3]环烷和24+带电荷的[5]环烷。
