Rotaxanes can be regarded as storage systems for their wheel components, which broadens their application potential as a complement to the supramolecular systems that retain a mechanically interlocked structure. However, utilising rotaxanes in this way requires a method to release the wheel while preserving the integrity of all molecular constituents. Herein, we present simple rotaxanes based on cucurbit[6]uril (CB6), with an axis equipped with an additional binding motif that enables the binding of another macrocycle, cucurbit[7]uril (CB7).

We combined two p-phenylenediamines (p-PDA) with a biphenyl (BiPhe) unit to prepare a supramolecular guest 4 consisting of three binding sites for cucurbit[7/8]uril (CBn) and/or cyclodextrins (CD). Supramolecular properties of 4 were investigated using NMR, UV-vis, mass spectrometry and isothermal titration calorimetry.

- Researchers are exploring new binding motifs for developing multitopic molecular devices like switches and sensors in supramolecular chemistry.
- A rigid binding motif for cucurbit[6]uril (CB6) hasn’t been identified until now; this study presents model guests featuring unique structures with imidazolium and ammonium groups.
- Findings show that specific guests form stable inclusion complexes with CB6 and CB7, indicating that these binding motifs could be useful for creating advanced supramolecular components.
