Polymerized organogel particles formed and imprinted by chiral gelators and their selective adsorption for phenylalanine racemates

Abstract

Novel polymerized supramolecular organogel particles were prepared by gelation and subsequent suspension polymerization. Herein, gelator was also used as a chiral template. After extraction of the gelator with ethanol, imprinted supramolecular organogel particles were obtained. SEM analysis of the particles showed porous structures after ethanol extraction. The imprinted particles were loaded as a stationary phase into a column to separate L- and D-phenylalanine racemic mixtures. The circular dichroism (CD) and optical rotation of the racemic mixtures that flowed through the column indicated that the imprinted supramolecular organogel particles exhibited distinct selective adsorption for L-phenylalanine.
