Probes to dye for: Rhodamine-inspired Si-pyronine, Si-rhodamine, Te-rhodamine, and Changsha NIR dyes have been developed recently. These dyes show fluorescence in the far-red to near-infrared region, while retaining the advantages of the original rhodamines, such as high fluorescence quantum yield, tolerance to photobleaching, good water solubility, and exhibit great potential for biological application.
