Sorption and Separation of Optical Isomers of 2-Butanol by Chiral Porous Coordination Polymers
Theor. Exp. Chem. 2015, 51 (1), 45-53
It was shown that porous coordination polymers (PCPs) of 3d metals containing chiral centers in fragments of deprotonated (S)-lactic and (R)-aspartic acid or trimesoyl-(S)-alanine are characterized by different values of sorption capacity with respect to the individual optical isomers of 2-butanol upon sorption of such substrates from the gas phase. The difference between the sorption capacity values with respect to the (R) and (S) isomers of 2-butanol correlates with the value of the enantiomeric excess achieved upon separation of the alcohol racemate on the respective PCP by column chromatography.
