Development of a fluorescein analogue, TokyoMagenta, as a novel scaffold for fluorescence probes in red region

Article abstract of DOI:10.1039/c1cc00078k

We present a design strategy for fluorescence probes with a high off/on activation ratio in the red wavelength region, based on a novel fluorescein analogue in which the O atom at the 10 position of the xanthene chromophore is replaced with a Si atom. To
