Intervalence Transfer in Dinuclear and Oligonuclear Polymetallic Assemblies. Mixed-valence compounds (such as the pigment Prussian Blue) have been known for over two centuries, and possess important conductivity, magnetic and spectral properties. Electron transfer between the elements of different valency (intervalence charge transfer, IVCT) gives rise to absorbances in the red or near-infrared region of the spectrum which provide fundamental information on the electron migration.

Mixed-valence compounds (such as the pigment Prussian Blue) have been known for over two centuries, and possess important conductivity, magnetic and spectral properties. Electron transfer between the elements of different valency (intervalence charge transfer, IVCT) gives rise to absorbances in the red or near-infrared region of the spectrum which provide fundamental information on the electron migration. By design of target di- and higher nuclearity polymetallic species, the project will study IVCT phenomena to understand electron movement, allowing rational development of applicable materials such as catalysts, light-activated devices and non-linear optical materials.Read moreRead less
