| 1 | Efficient Extraction of Lithium Ions from High Mg/Li Ratio Brine through the Synergy of TBP and Hydroxyl Functional Ionic Liquids显示文摘of main observation and conclusion The extraction of Li^+from the high Mg/Li ratio brine was performed using hydroxyl functional ionic lic-uids(ILs)as the coextractant and tributyl phosphate(TBP)as the extractant.irsty the extractive system,1-2-hydroxyethyl-3-mnethylimidazolumbis(trifuoromethylsulfonyl)imide([HOEmim][NTf2])+TBP was proved to exhibit the highest extraction efficiency of Li^+(88.15%)from LiCl aqueous solutions among the extractants composed of differents TB P,and ls+TBP.Effects of various extraction parameters on the extraction eficiencies of Li^+and Mg^2+were then investigated.95.01%of Li^+was extracted and the Li^+/Mg^2+separation factor reached 405.76 in a singl-stage at 278.15 Kand O/A of 2:1.The extraction complexes were determined by the slope analysis method and ESI-MS analysis,and the metal complexes in the organic phase were indcated to be mainly[L-2TBP][NTf;J.The striping study showed that 92.86%of i*was stripped with 1.0 mol·L^-1 HCl.98%extraction capacity of the synergyextractants was remained after 5 regeneration cycles.The thermodynamic parameters(△G°,△H°,and△S°),together with the mechanism of the Li^+extraction were further demonstrated finally,According to the results,[HOEmim][NTf2]+TBP extraction system showed promising performance in extracting lithium from salt lake brine with high Mg/Li ratio. | Ruibing Bai Junfeng Wang Li Cui Shicheng Yang Wei Qian Penglei Cui Yanqiang Zhang | 2020 | Chinese Journal of Chemistry2020，38，12： | 4 |

| 3 | Biomimetic Recognition of Organic Drug Molecules in Water by Amide Naphthotubes显示文摘Molecular recognition in water is the basis of numerous biological functions.The key for efficient and selective recognition of an organic drug molecule is to bind both its polar and nonpolar groups.This is achieved by bioreceptors for which specific noncovalent interactions are efficiently used in a hydrophobic pocket.In contrast,most synthetic receptors cannot efficiently bind the neutral,polar groups of drug molecules and,thus,often exhibit poor binding selectivity and affinity.In this research,we report a systematic study on the binding behaviors of three types of macrocyclic hosts(amide naphthotubes,cucurbit[7]uril,andβ-cyclodextrin)to 18 model compounds and 13 drug molecules.Our results show that the high desolvation penalty of polar groups of guests is the reason for the relatively low binding affinity of cucurbit[7]uril andβ-cyclodextrin.However,amide naphthotubes with a biomimetic cavity bind efficiently and selectively to organic guests through hydrophobic effects and hydrogen bonding.Drug molecules with multiple polar groups can be better accommodated by these naphthotubes.The anti-configured naphthotube show good biocompatibility according to preliminary cell experiments and is capable of enhancing the water solubility of two poorly soluble drug molecules.Therefore,they may have practical applications in pharmaceutical sciences. | Yan-Long Ma Mao Quan Xiu-Lian Lin Qian Cheng Huan Yao Xi-Ran Yang Ming-Shuang Li Wei-Er Liu Lin-Ming Bai Ruibing Wang Wei Jiang | 2021 | CCS Chemistry2021，3，4： | 0 |
