| 1 | Supramolecular Self-assembly Formed from Cucurbit[8]uril and p-Hydroxybenzoic Acid显示文摘The binding behavior of cucurbit[8]uril(Q[8])and p-hydroxybenzoic acid(p-HBA)has been investigated using ^(1)H NMR titration experiments,UV-Vis absorption,isothermal titration calorimetry(ITC),and X-ray crystallography.Results revealed that the Q[8]can accommodate two p-HBA molecules to form a 1:2 host-guest inclusion complex in solution,namely(p-HBA)2@Q[8].From a poorly scattering crystal,we were able to identify two symmetry unique Q[8]rings,but with different p-HBA fillings.The structure can be represented as Q[8]+1.5 p-HBA,which gives Q[8]@(p-HBA)2∙Q[8]@p-HBA as the structural formula.This supramolecular structure was screened for its ability to capture iodine.The experimental results showed that the adsorption efficiency of the supramolecular organic framework material for iodine capture was 43.8%,with an equilibrium adsorption capacity of 223.3 mg/g. | WANG Chenghui YU Zhichao BAI Qinghong PAN Dingwu PRIOR Timothy J TAO Zhu REDSHAW Carl XIAO Xin | 2023 | Chemical Research in Chinese Universities2023，39，6： | 0 |
| 2 | Double-cavity nor-seco-cucurbit[10]uril-based supramolecular assembly for selective detection and removal of trinitrophenol显示文摘The effective removal and selective detection of explosive and toxic pollutant trinitrophenol (TNP) is an attractive but challenging field.Herein,a double-cavity nor-seco-cucurbit[10]uril (ns-Q[10])-based supramolecular assembly 8-HQ@ns-Q[10]was fabricated and its structure was characterized by X-ray single crystal diffraction.In this assembly,the stoichiometric ratio of ns-Q[10]and 8-hydroxyquinoline (8-HQ) is 1:2,which is also attributed to the special double-cavity structure of ns-Q[10].The luminescence sensing experiments showed that 8-HQ@ns-Q[10]can be used as a good fluorescence-enhanced sensing material (enhanced 27-fold) for the rapid detection of explosives and the aqueous contaminant TNP,with a limit of detection (LOD) of 2.07×10^(-5)mol/L,without interference from other phenolic compounds.Furthermore,TNP can be efficiently removed in the presence of assembly 8-HQ@ns-Q[10],and the removal efficiency is more than 89%.Therefore,the supramolecular assembly 8-HQ@ns-Q[10],as a fluorescenceenhanced luminescence sensor and adsorption material,has rich research value and potential application prospect when applied to the detection and removal of TNP in aqueous environment. | Ran Cen Ming Liu Jiao He Dingwu Pan Lixia Chen Ying Huang Zhu Tao Xin Xiao | 2023 | Chinese Chemical Letters2023，34，10： | 0 |
