Title: Functionalized Block-Copolymer Templates for Synthesis and Shape Control of Quantum Dots

In this paper, a new quantum dot synthesis method based on metallic-block copolymer precursors was developed. The synthesis produced CdS QDs assembled into chains. This method provides a new model for the study of 1D QD chains to determine its effect on charge transport and optoelectronic coupling. This synthesis method was readily extended to other semiconductor materials including PbS and perovskites producing QDs of various shapes. Finally, it evidenced further promise of this synthesis method to assist in the assembly, shape and size control of various nanomaterials.
