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