center to produce the fluorescent dye. The disclosed dyes combine longer Stokes shifts (approximately 100 nm) with increased quantum yields. They are also photostable in aqueous and organic solutions for several hours. These dyes may be used in the labeling of biomolecules for bioimaging and assays. Also disclosed are methods for the synthesis of these dyes.

To dye for: Three related families of fluorescent dyes, rigidified by borondifluoride and based on bidentate anilido‐pyridyl donor ligands, are reported (see picture). The dyes show quantum yields up to 0.75 and improved Stokesshifts of >100 nm relative to the widely employed BODIPY family of dyes. Furthermore, the new dyes are exceptionally photostable and membrane‐specific.
