Selective gradient separation of aminophenol isomers by cucurbit[6]uril

Potential of nonporous adaptive crystals for hydrocarbon separation

“…Besides, H13a could also separate p-aminophenol from a mixture of aminophenol isomers with a purity of 94.16%. 183 These works illustrate the potential application of CB [6]-based NACs in industrial separation.…”

Double-cavity cucurbiturils: synthesis, structures, properties, and applications

“…, pH, electrochemical, chemical, and photochemical), and the low polarizability of the Q[ n ] cavity. 29,30,55,68–71 Therefore, Q[ n ]s have been effectively utilized to develop drug-delivery systems, 62,72,73 engage in biomolecular recognition, 74,75 create adsorptive separation materials, 76–80 fabricate supramolecular polymers, 81–85 and to establish chemical sensing ensembles. 86–88…”

“…51,58,[60][61][62][63][64][65][66][67][68][69][70] The defining molecular recognition properties of Q[n] hosts include their high affinity and selectivity [62][63][64][65][66][67] toward hydrophobic dications in water, their constrictive binding, their high stimulus responsiveness (e.g., pH, electrochemical, chemical, and photochemical), and the low polarizability of the Q[n] cavity. 29,30,55,[68][69][70][71] Therefore, Q[n]s have been effectively utilized to develop drug-delivery systems, 62,72,73 engage in biomolecular recognition, 74,75 create adsorptive separation materials, [76][77][78][79][80] fabricate supramolecular polymers, [81][82][83][84][85] and to establish chemical sensing ensembles. [86][87][88] Double-cavity Q[n]s are distinguished not only by their novel structures but, more significantly, by their unique properties.…”

Metal Cation-Doped ns-Cucurbit[10]uril: Adsorption of Para-Phenylenediamine

“…The emergence and rapid development of cucurbit­[ n ]­urils as the fourth class of host macrocycles have been witnessed in the past few decades. − Their distinctive pumpkin-shaped structures and diverse host–guest properties have garnered extensive applications. − Additionally, there have been reports on the utilization of permanently porous cucurbit­[ n ]­uril crystals as adsorbent materials. − Huang’s group recently reported cucurbit[6]­uril as an ideal material for the separation of pyridine and toluene . However, the existing macrocyclic compounds are mainly dominated by a single cavity, and their application capabilities may be limited by the size and number of cavities.…”
