Abstract:
Reminiscent of the ringed planet Saturn, new cucurbit[n]uril (CB[n]) derivatives CB*[5] and CB*[6] have rings decorating the "equator". The rings in this case are five- and six-fused cyclohexane rings, respectively (the structure of CB*[6] is shown). The remarkable solubility of the new CB[n] derivatives in water and organic solvents allows not only their unusual binding properties toward metal and organic ions in neutral water but also their applications in ion-selective electrodes to be studied.

Physical Properties Affecting Solubility
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...
