This project, funded by the Inorganic, Bioinorganic and Organo-metallic Chemistry Program, involves the study of tellurolate and selenolate ligands with both main group and transition metal centers. The focus is on ligands that contain bulky alkyl, silyl or aryl substituents such that monomeric complexes are formed. Studies of the reactivity of these complexes will include chalcogenide displacement/substitution, insertions into the M-ER (E = Te, Se) bond, reactions of the E center, and cleavage of the E-R bond. The long term objective of the research is to put this chemistry on the same basis as the much studied alkoxide and sulfide congeners. The potential for use of the molecular chalcogenide compounds as precursors for solid-state, materials will be examined as part of the project. %%% This project involves the study of the fundamental chemistry of selenium and tellurium. Unlike the lighter elements in this family (the chalcogenides), relatively little attention has been given to the molecular chemistry of these elements, primarily because of the difficulty of working with them. This is in spite of the fact that they are constituents of technologically important devices such as infrared detectors rechargeable batteries, photothermic imaging materials and photovoltaic solar cells to name a few. Professor Arnold, an excellent synthetic inorganic chemist, has laid the groundwork that could lead to some exciting advances in the chemistry of these elements and potentially to advances in technology arenas as well.
