pseudo[1]Catenane 3 is in a self-included conformation in chloroform, but in dichloromethane, it exists in an equilibrium between the self-included conformational state and a de-threading one. The planar chirality inversion of 3 can be triggered by the host-guest complexation of 3 with adiponitrile G, but the extent of such chiral switching depends on the length of self-included bis(pyrazin-2-yloxy)alkane chains in 3 - longer chains are more favored than shorter ones in the inversion.
伪轮烷 3 在氯仿中处于自身包含构象，但在二氯甲烷中，它存在于自身包含构象状态和脱螺纹构象之间的平衡中。3 与己二腈 G 的主体-客体络合可以触发 3 的平面手性反转，但这种手性转换的程度取决于 3 中自身包含的双（吡嗪-2-氧基）烷链的长度 - 较长的链比较短的链更有利于反转。
