合成了具有手性表面皲裂层的半导体纳米晶体，并通过手性性质、手性识别和自组装成手性超结构的研究证明了基于半导体纳米晶体的手性化学。基于CdS纳米晶体的圆二色性随尺寸的变化，提出了CdS纳米晶体色性的来源。具有手性表面配体的CdTe纳米晶体的光致发光响应于对映体，从而显示了手性传感能力。最后，研究了具有手性表面的碲化镉纳米晶体的自组装。

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.
