To provide an organic electroluminescence device having a high luminous efficiency and a novel compound that can be used as a material for an organic electroluminescence device having a high luminous efficiency.
A compound represented by the following formula (3-I), wherein at least one of R1 to R7 and R10 to R11 is —N(R36)(R37). R31 to R37 are independently a hydrogen atom, a substituted or unsubstituted alkyl group including 1 to 50 carbon atoms, a substituted or unsubstituted cycloalkyl group including 3 to 50 ring carbon atoms, a substituted or unsubstituted aryl group including 6 to 50 ring carbon atoms or a substituted or unsubstituted monovalent heterocyclic group including 5 to 50 ring atoms.

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.
Herein are disclosed fluorescent dyes based around a framework for a ligand comprising a pyridyl group linked to a diaryl anilido unit. A variety of ligands based on this framework are disclosed. The ligands chelate to a BF

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.
