[14] High Stokes Shift Anilido-Pyridine Boron Difluoride Dyes

Angew. Chem. Int. Ed. 2011, 50, 12214.

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.
