  • Fluorescent dyes
    Patent number: 7781187
    Abstract: Fluorescent dyes useful for detecting a target material in biological assays an electron donating moiety which is linked by a conjugated ?-electron bridge to an electron accepting moiety. The ?-electron bridge includes at least one carbocyclic ring structure or heterocyclic ring structure. The electron accepting moiety is a carboxylic acid, a salt of a carboxylic acid, or has the formula: wherein: X8 is selected from the group consisting of H, CH3, and (CH2)n6-Z2?, where Z2? is a monovalent anion; and n6 is an integer from 1 through 10; and Q3 is O or S.
    Type: Grant
    Filed: December 30, 2005
    Date of Patent: August 24, 2010
    Assignee: Corning Incorporated
    Inventors: Susan Marie Gasper, Mingqian He, Fang Lai, Thomas Mark Leslie, Helen Samson

  • Low loss high refractive index vinyl sulfide compounds and method of making same
    Patent number: 7148383
    Abstract: The invention is directed to aromatic vinyl sulfide compounds of general formula A(—S—CH?CH2)z, wherein z is in the range of 1–4 and A represents highly halogenated and highly halogenated-deuterated phenyl, biphenyl and naphthalene compounds; highly halogenated and highly halogenated-deuterated biphenyl ethers and thioethers; and highly halogenated and highly halogenated-deuterated unsaturated 5- and 6-member heterocyclic ring systems containing carbon and at least one heteroatom selected from the group consisting of nitrogen, oxygen and sulfur. The aromatic vinyl sulfide compounds of the invention can be used to prepare elements and devices suitable for use in optical communications.
