“…The isolation and characterization of the first member of this family, cucurbit [6]uril was reported in 1981 by Mock [15], which allow it to form stable host-guest complexes with several different types of guests in its hydrophobic cavity because of a combination of non-covalent interactions including the hydrophobic effect, ion-dipole interactions, and hydrogen bonding [16]. Cucurbituril as adsorbent for the removal of reactive dyes has been reported [17,18]. However, acids and cations in water increase the solubility of CB [6]; thus, CB [6] cannot be used as a sorbent.…”

2015) Adsorption of sulfamonomethoxine antibiotics to cucurbit[6]uril polymer: kinetics and thermodynamic studies, Desalination and Water Treatment, 54:1, 113-121, A B S T R A C TThe occurrence of sulfonamide antibiotics in aquatic environments has been recognized as a significant issue warranting focused attention. A cucurbituril polymer (CP) was used as an adsorbent for sulfamonomethoxine (SMM) in aqueous solution. The experimental isotherm data were analyzed using non-linear Freundlich and Henry isotherm equations. Five error functions were used to predict the parameters of the isotherm. The Freundlich model had performed better with respect the equilibrium data and the HYBRID error function provided the lowest sum of normalized error. Our thermodynamic investigation indicated that the adsorption of SMM onto CP was spontaneous at all temperatures and was an exothermic process. The pseudo-first-order and pseudo-second-order kinetic model were used to fit the kinetics process of SMM adsorption on CP. The adsorption of SMM could be best described by the pseudo-second-order equation. The intra-particle diffusion model was used to further analyze the diffusion mechanism of SMM on CP. The result implies that intra-particle diffusion is not the only rate-limiting step. And the adsorption was favorable in the pH range of 2.0-6.0. The results indicate that CP could serve as alternative adsorbent for removing SMM antibiotics from water.

“…However, acids and cations in water increase the solubility of CB [6]; thus, CB [6] cannot be used as a sorbent. Hence, Karcher proposed that CB [6] should be attached to a carrier in order to produce a useful sorbent [18]. Our team has used cucurbit [6]urilanchored silica gel (ACB [6]-SG) as adsorbent for sulfamonomethoxine (SMM) [19].…”

“…After being cooled to room temperature, the resulting precipitate was removed by filtration, and the filtrate was concentrated to 25 mL. Acetone diffusion to the resulting solution gave a white precipitate which was collected by filtration, washed with acetone, and dried in a vacuum to give [7] and CB [8], however, it produces the corresponding perhydroxyCB[n] (n ) 7 or 8) only in ∼5% yield, which may be due to a much lower stability of the products. The perhydroxy derivatives (HO) 14CB [7] and (HO)16CB- [8] have been characterized by NMR and mass spectrometry (see Supporting Information).…”

Facile Synthesis of Cucurbit[n]uril Derivatives via Direct Functionalization: Expanding Utilization of Cucurbit[n]uril

A long-standing problem in cucurbituril chemistry is answered through the first direct functionalization of cucurbit[n]uril (CB[n]; n = 5-8)) leading to perhydroxyCB[n] which can be further modified to provide tailored CB[n] derivatives with desired functional groups and good solubility. Anchoring a CB[6] derivative on the surface and its potential application as a sensor are demonstrated. A CB[6] derivative forms nanospheres with possible use in protein and peptide drug delivery.
