The macrocyclic cavitand is used as a template for the mechanochemical synthesis of 0.2@RHO-Zn() (0.2@ZIF-71) and RHO-Zn (ZIF-11) zeolitic imidazolate frameworks (ZIFs). It is shown that significantly accelerates the mechanochemical synthesis, providing high porosity products (BET surface areas of 1140 m/g and 869 m/g, respectively). Templation of RHO-topology ZIF frameworks constructed of linkers larger than benzimidazole (HBIm) was unsuccessful. It is also shown that cavitands other than -namely , , , , , -can serve as effective templates for the synthesis of (cavitand)@RHO-ZnIm products. The limitations on cavitand size and shape are explored in terms of their effectiveness as templates.

大环穴状配体被用作机械化学合成 0.2@RHO-Zn()（0.2@ZIF-71）和 RHO-Zn（ZIF-11）沸石咪唑酯骨架（ZIF）的模板。结果表明，它显著加速了机械化学合成，提供了具有高孔隙率的产物（BET 比表面积分别为 1140 m/g 和 869 m/g）。用大于苯并咪唑（HBIm）的连接体构建的 RHO-拓扑 ZIF 骨架的模板化不成功。还表明，除了 -以外的其他穴状配体 -， -， -， -， -， -可以作为合成（穴状配体）@RHO-ZnIm 产物的有效模板。根据它们作为模板的有效性，探索了穴状配体尺寸和形状的限制。
