Chem. Eur. J. 2015, accepted.

A systematical extension of “string” molecules for CB6-encapsulated pseudorotaxanes from 1,4-butyl (C4) to 1,5-pentyl (C5) and 1,6-hexyl (C6), which affords different configurations of pseudorotaxanes ligands, and further lead to progressive weakening of supramolecular inclusion interactions after hydrolysis of cyano groups and deprotonation of diammonium motifs, induces the configuration inversion of pseudorotaxane spacers and finally two new tetranuclear uranyl-directed square wave-like polyrotaxanes.
