We have reported that functionalization of achiral colloidal quantum dots (QDs) with chiral organic capping ligands by phase transfer ligand exchange as a simple yet powerful method for the induction of chirality in QDs. Yet, the presence of chiral capping ligands on the surface of CdSe QDs was necessary but not sufficient condition for the induction of optical activity in QDs, and several chiral ligand failed to induce chirality in QDs. We will present a newly developed water-free and purification-free ligand exchange protocol for the synthesis of chiral QDs as well as the optical and chiroptical properties of the newly acquired chiral QDs. Relationship between chemical structure of the amino acid capping ligands and the induced circular dichroic properties of QDs will be elucidated.
