"Precision Synthesis of Semiconductor Nanoclusters: Connecting Coordination, Cluster, and Colloidal Chemistry"

Semiconductor nanomaterials have broad applications in energy, information, and biomedical nanotechnologies. Achieving atomic-level control in semiconductor nanomaterials is crucial for their reproducible synthesis, consistent properties, and precision engineering. However, this has been a significant challenge due to the structural complexity of nanomaterials and their entangled reaction kinetics. Here, I will show our recent progress in combining coordination, cluster, and colloidal chemistry to achieve atomic precision in semiconductor nanoclusters. The development of precise nanoscale reactions has enabled us to answer some important questions, including (i) how different ligands collaboratively passivate the nanocrystal surfaces, (ii) the origin of chirality and polarity in semiconductor nanostructures, (iii) the precise correlation between the excitonic transitions and electronic structures, and (iv) the atomic-level insights into the intricate reaction mechanisms. We expect that precision nano-synthesis will enable designer semiconductor nanocrystals with atomically tailored properties for their optical, electronic, and spin-based applications.
