The family of dyes of the invention are fluoresceins and rhodols that are directly substituted on one or more aromatic carbons by fluorine. These fluorine-substituted fluorescent dyes possess greater photostability and have lower sensitivity to pH changes in the physiological range of 6-8 than do non-fluorinated dyes, exhibit less quenching when conjugated to a substance, and possess additional advantages. The dyes of the invention are useful as detectable tracers and for preparing conjugates of organic and inorganic substances.
本发明的染料系列是在一个或多个芳香碳上直接被氟取代的荧光素和荧光铑。与非氟化染料相比,这些氟取代的荧光染料具有更高的光稳定性,在 6-8 生理范围内对 pH 值变化的敏感性较低,与物质共轭时淬灭程度较低,并具有其他优点。本发明的染料可用作可检测的示踪剂,也可用于制备有机和无机物质的共轭物。
