The invention relates to novel and improved photostable rhodamine dyes of the general structural formulae I or II and their uses as fluorescent markers, e.g. for immunostainings and spectroscopic and microscopic applications, in particular in conventional and stimulated emission depletion (STED) microscopy and fluorescence correlation spectroscopy. The partially deuterated analogues are useful as molecular mass distribution tags in mass spectroscopic applications. wherein R1 = an unsubstituted or substituted alkyl group, including a cycloalkyl group, or heterocylcoalkyl group; R2 = H, an unsubstituted or substituted alkyl group, including a cycloalkyl group, or heterocycloalkyl group, or an unsubstituted or substituted aryl group or heteroaryl group, or any combination of such groups; X = CH2, C=O, C=NORa, C=NNRaNRb, CH (ORa), O, S, SO, SO2, or any other derivatives of these groups, with Ra and Rb independently being H or an organic residue, in particular an unsubstituted or substituted (cyclo) alkyl group or heterocycloalkyl group, an unsubstituted or substituted aryl group or heteroaryl group; Z = a negatively charged group with 1, 2, 3, 4 or 5 charges per anion.
本发明涉及一种新型和改进的光稳定的罗丹明染料,其一般结构式为I或II,以及它们作为荧光标记物的用途,例如用于免疫染色、光谱和显微应用,特别是在传统和受激发射抑制(STED)显微镜和荧光相关光谱中的应用。部分氘代类似物可用作质谱应用中的分子质量分布标记。其中,R1 = 未取代或取代的烷基,包括环烷基或杂环烷基;R2 = H,未取代或取代的烷基,包括环烷基或杂环烷基,或未取代或取代的芳基或杂芳基,或这些基团的任何组合;X = CH2,C=O,C=NORa,C=NNRaNRb,CH(ORa),O,S,SO,SO2或这些基团的任何其他衍生物,其中Ra和Rb独立地为H或有机残基,特别是未取代或取代的(环)烷基或杂环烷基,未取代或取代的芳基或杂芳基;Z = 带有1、2、3、4或5个负电荷的阴离子基团。
