title: 6-TIPS-β-Cyclodextrin-Modified Fe3O4for Facile Enantioseparation of 1-(1-Naphthyl)ethylamine.
abstract: A new type of chiral magnetic nanoparticle was prepared from covalently linked magnetic nanoparticles (Fe3O4) and heptakis-(6-O-triisopropylsilyl)-β-cyclodextrin (6-TIPS-β-CD). The resulting selectors (TIPS-β-CD-MNPs) combined the good magnetic properties Fe3O4and efficient chiral recognition ability of 6-TIPS-β-CD. The enantioselectivity of TIPS-β-CD-MNPs towards 1-(1-naphthyl)ethylamine was six times higher than that of the parent β-CD modified Fe3O4particles.
