A general route for the synthesis of asymmetric catenanes with multiple, different functional groups was established. There were many synthetic challenges involved in the synthesis. For example, the solubility of the key intermediates needed to be finely tuned, and the compatibility of various protecting groups required careful consideration. Now a variety of catenanes with asymmetric rings can be readily synthesized.As for the formation of MOF, it was found that the functional groups in catenane ligand affect the formation of the crystal, as well as the morphology of the crystal. However, crystals which are good enough for further characterization have not been successfully obtained.

建立了与多个不同官能基团合成不对称catenanes的一般途径。合成涉及许多综合挑战。例如，需要对关键中间体的溶解度进行细微调整，并且各种保护组的兼容性需要仔细考虑。现在，可以很容易地合成各种具有不对称环的蛋糕。因为对于MOF的形成，发现Catenane配体中的官能团会影响晶体的形成，以及晶体的形态。但是，尚未成功获得足够好的进一步表征的晶体。
