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.
该发明的染料家族是直接在一个或多个芳香碳上被氟取代的荧光素和罗丹素。这些氟取代的荧光染料具有更高的光稳定性,在生理范围为6-8的pH变化下比非氟化染料具有较低的敏感性,当与物质结合时表现出较少的猝灭,并具有额外的优势。该发明的染料可用作可检测的示踪剂,并用于制备有机和无机物质的共轭物。
