Tetra-hydro-quinoxaline (THQ) moiety was used as the electron donor in the construction of a series of red-emitting iminocoumarin-based borate dyes with good fluorescent quantum yields, large Stokes shifts and long-wavelength emissions. These dyes could stain cells and image zebrafish with good performance.

Complexation of iminocoumarin derivatives with BF3·OEt2 provides novel N⁁N boron(III) dyes exhibiting high absorption coefficients and quantum yields as great as 81%. The excellent chemical stability of these dyes enables the grafting of Boranil or Bodipy units to give derivatives in which the Borico subunit can act either as an energy acceptor or as an antenna for a red emitting fluorophore.
