NOVEL FLUORINATED RHODAMINES AS PHOTOSTABLE FLUORESCENT DYES FOR LABELLING AND IMAGING TECHNIQUES

摘要

The present invention relates to novel fluorinated 3,6- diaminoxanthene compounds derived from the basic structural formula (I) and to their uses as photostable fluorescent dyes, e.g. for immunostainings and spectroscopic and microscopic applications, in particular in conventional microscopy, stimulated emission depletion (STED) reversible saturable optically linear fluorescent transitions (RESOLFT) microscopy, and fluorescence correlation spectroscopy. The claimed compounds are also useful as molecular probes in various spectroscopic applications.
