  • Title: Decorated traditional cellulose with nanoscale chiral metal-organic frameworks for enhanced enantioselective capture.
    Author: Guo Y, Zhang L, Wang K, Yu A, Zhang S, Ouyang G.
    Journal: Chem Commun (Camb); 2021 Oct 07; 57(80):10343-10346. PubMed ID: 34528980.
    Abstract:
    Herein, a rapid approach toward the size/morphology-controlled synthesis of [Cu(L-mal)(bipy)·2H2O] (CuLBH) was developed by adjusting the concentrations of 2-methylimidazole (2-MI) and copper ions. The chiral separation efficiency test indicated that the nano-diameter CuLBH exhibited better selective potential towards (±)-1-(1-naphthyl)ethanol (NE) by providing more fully exposed recognition sites. In order to further improve the selectivity for NE enantiomers and avoid the aggregation of MOF nanoparticles, the nanosized CuLBH-decorated carboxylated cellulose (CC) composite CC-CuLBH was designed by controlling the ratio of the solvent and Cu2+, which exhibited much higher enantioselectivity than those of pristine CC and even nano CuLBH.
