Cucurbit[N]Uril-Calix[N]Arene-Based Supramolecular Frameworks Assembled Using The Outer Surface Interactions Of Cucurbit[N]Urils

Based on the crystal structures of two cucurbit[6]urilicalix[n]arene-based supramolecular frameworks reported by Long and co-workers, we further investigated the interactions of cucurbit[6]uril with 4-sulfocalix[4]arene and 4-sulfocalix[6]arene using H-1 NMR spectroscopy and isothermal titration calorimetry (ITC), respectively. Moreover, solid fluorescent materials were prepared via the adsorption of fluorescent dyes by these porous supramolecular frameworks, which exhibit a selective response to certain volatile organic compounds.
