Atomically precise metal nanoclusters are novel materials that have the potential to address everyday needs from energy to health. Luminescent metal clusters can be used for effective and efficient energy harvesting and conversion technologies, while water-soluble luminescent metal clusters offer more efficient and personalized biomedical approaches. Furthermore, nanoclusters can be used as building units to form higher-dimensional cluster-assembled materials and can modulate the optoelectronic properties of desired device materials. To create a hierarchy of structures and applications, a fundamental understanding of the structure-property relationship at the atomic level is vital.
This special themed collection aims to look at new structures, photophysical, chemical and electrochemical catalysis reactions, and structure-property correlations within the themes of atomically precise metal nanoclusters. The collection covers new nanocluster structures, transformation reactions, luminescent materials, light-matter interactions, catalysis (photocatalysis and electrocatalysis), bioimaging and sensing, drug delivery, optoelectronic devices and new techniques for characterization.
