A Three-Dimensional Polyrotaxane Network

Abstract

Cucurbituril is used as the molecular “bead” for the synthesis of the first three-dimensional polyrotaxane network, which shows an inclined α-polonium topology. The novel solid-state interlocked structure is made up of binulcear Tb3+ centers and pseudorotaxane units containing cucurbituril “beads” threaded on a “string” with 3-phenylcarboxylate terminals (shown schematically).
