  The present invention comprises 6,8-difluoro-7-hydroxycoumarins and derivatives of 6,8-difluoro-7-hydroxycoumarins, including reactive dyes, dye-conjugates and enzyme substrates. These fluorine-substituted fluorescent dyes typically possess greater photostability and lower pH sensitivity in the physiological pH range than their nonfluorinated analogs, exhibit less fluorescence quenching when conjugated to a substance, possess absorption and emission spectra that closely match those of their nonfluorinated analogs, and also exhibit higher quantum yields than their nonfluorinated analogs.

  本发明包括6,8-二氟-7-羟基香豆素及其衍生物，包括反应染料、染料共轭物和酶底物。这些氟取代的荧光染料通常具有比其非氟取代的类似物在生理pH范围内更高的光稳定性和较低的pH敏感性，当与物质结合时，表现出较少的荧光猝灭，具有吸收和发射光谱与其非氟取代的类似物非常接近，并且比其非氟取代的类似物具有更高的量子产率。
