Abstract
The relationships between charge-localization processes in chemistry and physics are explored. Origin of the basic ideas is traced from the conception of quantum mechanics to the present day. Independent work in physics (Anderson localization, Mott metal-insulator transitions, BCS superconductivity) and chemistry (electron-transfer theory, mixed-valence spectroscopy) are discussed and parallels between them drawn. In particular, focus is placed on adiabatic electron-transfer theory, its broad-ranging physical significance, and its close connection with superconductivity and Mott localization. The revolutionary idea that chemical reaction rates could be predicted from knowledge of electronic absorption spectra is emphasised, as is the role of nuclear motion in controlling conductivity. Modern technological applications of adiabatic electron-transfer theory in understanding natural photosynthetic processes and the operation of organic artificial solar cells is discussed, as is the development of Molecular Electronics devices in which single molecules are used to transport, control, and store electrical current.
