Photocontrol over Cucurbit[8]uril Complexes: Stoichiometry and Supramolecular Polymers

Optical control over bioactive ligands at supramolecular surfaces

Addressing whole protein and bacterial immobilization and their optical control on a β-cyclodextrin supramolecular platform.

Efficient syntheses of pillar[6]arene-based hetero[4]rotaxanes using a cooperative capture strategy

While one pillar[6]arene, nestling between two cucurbit[6]urils in a hetero[4]rotaxane, is conformationally mobile in solution, it adopts the energetically most favourable conformation with local C_3V symmetry in the solid state.

Supramolecular polymerization of supramonomers: a way for fabricating supramolecular polymers

This communication describes a new method of fabricating supramolecular polymers through supramolecular polymerization of supramonomers.

Sequential inclusion of two berberine cations in cucurbit[8]uril cavity: kinetic and thermodynamic studies

The formation and dissociation kinetics of 1 : 1 and 2 : 1 inclusion of berberine in the cucurbit[8]uril cavity is revealed.

In situ SERS monitoring of photochemistry within a nanojunction reactor

We demonstrate a powerful SERS-nanoreactor concept composed of self-assembled gold nanoparticles (AuNP) linked by the sub-nm macrocycle cucurbit[n]uril (CB[n]). The CB[n] functions simultaneously as a nanoscale reaction vessel, sequestering and templating a photoreaction within, and also as a powerful SERS-transducer through the large field enhancements generated within the nanojunctions that CB[n]s define. Through the enhanced Raman fingerprint, the real-time SERS-monitoring of a prototypical stilbene photoreaction is demonstrated. By choosing the appropriate CB[n] nanoreactor, selective photoisomerism or photodimerization is monitored in situ from within the AuNP-CB[n] nanogap.
