A series of luminescent dipyrrins and their derivative metal complexes have been synthesized, including the first examples of paramagnetic, visibly luminescent dipyrrinato metal complexes.  The quenching effects of heavy atoms and paramagnetic metal ions on the luminescence intensity have been measured.  Quantum yields for fluorescence from these complexes are as high as 0.67.
