Soluble porphyrin-bisindolylmaleimides dyad and pentamer as saturated red luminescent materials

Novel soluble porphyrin-bisindolylmaleimides dyad and pentamer were prepared in which the bisindolylmaleimide groups function as the antenna to enhance intramolecular energy transfer to the porphyrin core. These compounds are good candidates of red-light emitting materials for organic light-emitting diodes (OLEDs).
