Abstract
Xanthene compounds are disclosed having fluorescence at multiple wavelengths. Also disclosed are methods for their synthesis and use. Some of the compounds fluoresce at three wavelengths, emitting white light. Uses include the imaging of biological tissues, illumination, and display technologies. Many of the compounds have large Stokes shifts, and are resistant to photobleaching. The fluorescence may be readily distinguished from that of endogenous fluorophores, and from that of most existing, commercially-available fluorescent probes. The compounds are well suited for use in 'multiplexing' techniques. They exhibit clear isosbestic and isoemissive points, and have broad absorption and emission ranges.
