(−)/(+)-Sparteine induced chirally-active carbon nanoparticles for enantioselective separation of racemic mixtures†
Abstract
Chiral carbon nanoparticles (CCNPs) were developed by surface passivation using the chiral ligand (−)-sparteine or (+)-sparteine (denoted (−)-SP/CNP and (+)-SP/CNP, respectively). The chirality of the prepared CCNPs was demonstrated by circular dichroism and polarimetry and employed as an enantioselective separation platform for representative racemic mixtures.
