REDOX-ACTIVE STRUCTURES AND DEVICES UTILIZING THE SAME

Patent number: 9309274

Abstract: 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 electro-density 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.

Publication number: 20110059536

Abstract: The present invention relates to a molecular-based system for the optical detection, quantification and detoxification of hexavalent chromium (Cr6+) by reversible metal-substrate electron transfer. More particularly, the invention provides a Cr6+ sensor device comprising a divalent osmium (Os2+)-, iron (Fe2+)- or ruthenium (Ru2+)-based pyridyl complex capable of changing its oxidation state in response to a reduction of Cr6+ at the presence of H+, thereby causing a reversible and optically readable change in optical properties of said complex. The Os2+-, Fe2+- or Ru2+-based pyridyl complex used according to the invention can be used for selective detection and quantification of Cr6+, as well as for catalytic detoxification of Cr6+.

HIGH-RESPONSE ELECTRO-OPTIC MODULATOR BASED ON AN INTRINSICALLY ACENTRIC, LAYER-BY-LAYER SELF-ASSEMBLED MOLECULAR SUPERLATTICE

Patent number: 6549685

Abstract: A new electro-optic (EO) phase modulator constructed from a combination of a low-loss passive polymer waveguide and a self-assembled chromophore superlattice (SAS) with an intrinsically polar microstructure. In contrast to typical polymer-based modulators, the present invention utilizes a siloxane SA methodology that enables the acentric alignment of constituent chromophores during film growth without the need for post-deposition electric field poling. The guiding layer is constructed of the SAS and the glassy polymer Cyclotene™. The use of SiO2, Cytop™ and Cyclotene™ glassy polymers, results in a straightforward device fabrication process that is compatible with the thermally and photochemically robust SAS. Thus, nanoscale control of the film architecture results in greatly simplified macroscopic device fabrication. The present invention provides a SAS-based electro-optic modulator demonstrating excellent electro-optic response properties and a phase shift.
