(给出化学方程式)极端的大环化！通过两端含有Pd II配位环的双环化合物(见结构)的可逆连接，定量地获得了主链上有238个非氢原子的超大环结构。Pd II环可以被认为是一个纳米级的反应中心，可以在没有高熵成本的情况下连接纳米级的组件。
(Chemical Equation Presented) Extreme macrocyclization! An ultramacrocyclic structure with 238 non-hydrogen atoms in its backbone is obtained quantitatively through the reversible catenation of a double-loop compound that contains Pd II-clipped coordination rings at both ends (see structure). The Pd II ring can be regarded as a nanoscale reaction center that is available for connecting nano-scopic components without high entropy costs.
