报告会摘要：
In very recent years, ultrasmall metal nanoclusters with core sizes below 2 nm have emerged as a new class of functional nanoparticles due to their discrete and size dependent electronic structures and molecular-like properties, such as HOMO-LUMO transitions in optical absorption, quantized charging, and strong luminescence. Synthesis of high quality metal nanoclusters in sufficiently large quantities is necessary for establishing reliable size-property relationships and exploring their potential applications. This presentation will summarize our recent progress in the development of novel synthetic strategies for the production of atomically precise metal nanoclusters. The preparation of atomically precise metal nanoclusters is viewed as engineerable process where both the precursors (input) and their conversion chemistry (processing) may be rationally designed to achieve the desired outcome – atomically precise metal nanoclusters (output). We will demonstrate several efficient strategies for tailoring the precursor and the conversion process, and present our understanding of the processes involved. We will also highlight some application developments of metal nanoclusters in important sustainability topics including sensors for the environment and human health, and other biomedical applications.
