6-TIPS-β-Cyclodextrin-Modified Fe 3 O 4 for Facile Enantioseparation of 1-(1-Naphthyl)ethylamine

A new type of chiral magnetic nanoparticle was prepared from covalently linked magnetic nanoparticles (Fe O ) and heptakis-(6-O-triisopropylsilyl)-β-cyclodextrin (6-TIPS-β-CD). The resulting selectors (TIPS-β-CD-MNPs) combined the good magnetic properties Fe O and efficient chiral recognition abilit...

Beschreibung
Zusammenfassung:	A new type of chiral magnetic nanoparticle was prepared from covalently linked magnetic nanoparticles (Fe O ) and heptakis-(6-O-triisopropylsilyl)-β-cyclodextrin (6-TIPS-β-CD). The resulting selectors (TIPS-β-CD-MNPs) combined the good magnetic properties Fe O and 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 Fe O particles.
