| Research Abstract |
Semiconductor nanocrystals with chiral surface chapping layer have been synthesized and the chiral chemistry based on the semiconductor nanocrystals were demonstrated by means of the investigations of chiroptical properties, chiral recognition and self-assembly into chiral superstructures. The origin of chiroptical property of CdS nanocrystal was proposed based on the change in circular dichroism profiles dependent on the size of nanocrystals. The photoluminescence of CdTe nanocrystals with chiral surface ligands was modulated in response to enantiomers, thus demonstrating the chiral-sensing capability. Finally, the self-assembly of CdTe nanocrystals with chiral surface was studied.
