Unprecedented Replacement of Bridging Oxygen Atoms in Polyoxometalates with Organic Imido Ligands

摘要

Polyoxometalates (POMs) are a rich and diverse family of metal-oxygen clusters made up of early transitional metals with unique photonic, electronic, and magnetic properties and chemical reactivity that has promised dramatic applications in quite diverse disciplines, including catalysis, medicine, and materials sciences. Nowadays, from traditional Lindqvist and Keggin POMs to A. Miiller and co-workers' nanotires and nanoballs, a wide structural variety of POMs has been obtained by chemists. Especially, among the reported nanoscale POMs, some POMs have been discovered to show remarkable self-assembly in solution or on surfaces, and even to function as artificial cells to model the transport of cations under physiological conditions.
