Abstract:
A photoelectric conversion device using a semiconductor fine material such as a semiconductor fine particle sensitized with a dye carried thereon, characterized in that the dye is a methine type dye having a specific partial structure, for example, a methine type dye having a specific carboxyl-substituted hetero ring on one side of a methine group and an aromatic residue substituted with a dialkylamino group or an organic metal complex residue on the other side of the methine group, or a methine type dye having a carboxyl-substituted aromatic ring on one side of a methine group and a heteroaromatic ring having a dialkylamino group or an organic metal complex residue on the other side of the methine group; and a solar cell using the photoelectric conversion element. The photoelectric conversion element exhibits a conversion efficiency comparable or superior to that of a conventionally known photoelectric conversion element sensitized with a methine type dye.

Abstract:
Chemically reactive carbocyanine dyes incorporating an indolium ring moiety that is substituted at the 3-position by a reactive group or by a conjugated substance, and their uses, are described. Conjugation through this position results in spectral properties that are uniformly superior to those of conjugates of spectrally similar dyes wherein attachment is at a different position. The invention includes derivative compounds having one or more benzo nitrogens.
Abstract:
The invention provides compounds and compositions of Formulas I-VII, and methods of using the compounds. The compounds can be used to prepare dye conjugates that are uniformly and substantially more fluorescent on proteins, nucleic acids or other biopolymers, than conjugates labeled with structurally similar known carbocyanine dyes. In addition to having more intense fluorescence emission than structurally similar dyes at virtually identical wavelengths, and decreased artifacts in their absorption spectra upon conjugation to biopolymers, the compounds can have greater photostability and/or higher absorbance (extinction coefficients) at the wavelength(s) of peak absorbance than such structurally similar dyes.
Abstract:
In various embodiments, the present invention provides fluorescent dyes that are linked to another species through an adaptor moiety. In an exemplary embodiment, the dye is linked to a polyphosphate nucleic acid through an adaptor. An adaptor can be a component of a linker. These conjugates find use in single molecule DNA sequencing and other applications. In various embodiments, the dye moiety is a cyanine dye. Cyanine dyes that are highly charged, such as those including multiple sulfonate, alkylsulfonate, carboxylate and/or alkylcarboxylate moieties are examples of cyanine dyes of use in the compounds of the invention.
