    摘要： A device is presented having reversibly changeable and optically readable optical properties. The device comprises a substrate having an electrically conductive surface and carrying a redox-active layer structure. The redox-active layer structure may be a monolayer or a multi-layer structure and is configured to have at least one predetermined electronic property including at least one of electrodensity and oxidation state. The electronic property of the layer structure defines an optical property of the structure thereby determining an optical response of the structure to certain incident light. This at least one electronic property is changeable by subjecting the redox-active layer structure to an electric field or to a redox-active material. The device thus enables effecting a change in said electronic property that results in a detectable change in the optical response of the layer structure.

    摘要： Compositions and methods for modifying one or more biologic targets are provided. Suitable targets include cells, DNA, proteins, enzymes, and/or a subject in need thereof. The compositions may exist as a monomer or multimer and are active in a biologic environment with enhanced activity in hypoxic environments and, thus, exhibit improved specificity for hypoxic biologic targets (e.g., tumorigenic cells and those undergoing uncontrolled cell growth). A composition typically comprises a complex with an overall charge of 2+ or greater having at least one ruthenium atom attached to a redox active ligand. The redox active ligand helps maintain separation of more than one ruthenium atom. Suitable compositions may further include a terminal ligand comprising a heterocyclic aromatic compound. When provided to a biologic target, the composition modifies the biologic target and no additional compounds need be provided. Suitable compositions are typically catalytic and regenerative in the presence of a reducing agent.

The resulting noble metal complexes possess enhanced volatility and thermal stability characteristics, and are suitable for chemical vapor deposition(CVD) applications. The corresponding noble metal complex is formed by treatment of the FBC ligand with a less volatile metal halide. Also disclosed are CVD methods for using the noble metal complexes as source reagents for deposition of noble metal-containing films such as Ir, Ru and Os, or even metal oxide film materials IrO2, OsO2 and RuO2.
