Design and synthesis of responsive, elastic, porous single crystalline materials using mechanically interlocked molecules

建立了一条合成具有多个不同官能团的不对称链烷的一般路线。在合成过程中涉及到许多合成挑战。例如，关键中间体的溶解度需要微调，各种保护基团的相容性需要仔细考虑。现在可以很容易地合成各种具有不对称环的链烷。至于MOF的形成，人们发现猫烷配体中的官能团影响晶体的形成，以及晶体的形态。然而，还没有成功地获得足够好的晶体来进一步表征。

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.
