[4]Pseudorotaxanes with Remarkable Self-Sorting Selectivities

W. Jiang, D. Sattler, K. Rissanen, C. A. Schalley— 2011

The synthesis and characterization of several self-assembled [4]pseudorotaxanes is reported, some of which form in a programmed way based on two similar yet orthogonal crown ether/secondary ammonium ion binding motifs. A preference for the formation of a [4]pseudorotaxane with an antiparallel rather than parallel alignment of crown ether building blocks is observed even in the absence of such orthogonal binding sites, when a homodivalent axle is used.
