  • Patent number: 7888507
    Abstract: Novel energy transfer dyes which can be used with shorter wavelength light sources are provided. These dyes include a donor dye with an absorption maxima at a wavelength between about 250 to 450 nm and an acceptor dye which is capable of absorbing energy emitted from the donor dye. One of the energy transfer dyes has a donor dye which is a member of a class of dyes having a coumarin or pyrene ring structure and an acceptor dye which is capable of absorbing energy emitted from the donor dye, wherein the donor dye has an absorption maxima between about 250 and 450 nm and the acceptor dye has an emission maxima at a wavelength greater than about 500 nm.

  • Publication number: 20100076040
    Abstract: The invention relates to a method for producing bisbenzoxazoles that are interconnected by means of a system of conjugated double bonds, according to which o-aminophenols are reacted with dicarboxylic acids, the carboxyl groups of which are interconnected via a double bond or a system of conjugated double bonds, to form an ammonium salt, said ammonium salt being converted in the presence of dehydrogenating catalysts and solvents with a low dielectric loss into benzoxazol by means of microwave radiation.

  • Publication number: 20100015054
    Abstract: Disclosed are reactive polyfluoro benzoxazole polymethine dyes that are useful for labelling and detecting biological and other materials. The dyes are of formula (I): in which X is selected from the group consisting of —O—, —S— and at least one of groups R1 and R2 is the group -L-Rx or -L-Rp, where L is a linking group, Rx is a group suitable for covalent attachment of the dye to a component and Rp is a component; and at least one of groups R3, R4, R5, R6, R7, R8, R9 and R10 comprises fluorine. The use of polymethine dyes substituted by fluorine and having additional substitution by sulphonic acid groups, for labelling biological target molecules results in a labelled product in which there is reduced dye-dye aggregation and improved photostability, compared with cyanine dyes having no such substitutions.
