Technical notes on CB[10]

CB[10] has the largest cavity in the series (≈870 Å³; portal ≈8.9 Å) and can host bulky guests such as proteins, peptides, dendrimers, and nanoparticle surface ligands, enabling macromolecular encapsulation, supramolecular nanomaterial assembly, and protein-surface recognition. Due to isolation challenges, CB[10] is commonly reported in the literature as the CB[10]·CB[5] inclusion complex. When designing experiments, account for how this included guest affects cavity availability.

Storage, Solubility, and Handling Guidelines

Store sealed, dry, and protected from light at room temperature. For long-term storage, keep at 2–8 °C under dry conditions.
Cucurbituril powders are slightly hygroscopic. Reseal immediately after use and record the batch number and opening date.
Solubility tips: CB[7] and the modified series dissolve directly in water. For CB[6], first dissolve in formic acid or DMSO, then dilute into the target solvent system.
Filter stock host solutions and use them fresh; for binding experiments, record buffer composition, ionic strength, and pH.
