Divergent Reactivity of Diketopyrrolopyrroles: Ring-Opening with Amines

We report an unprecedented reaction of a diketopyrrolopyrrole (DPP) with primary and secondary amines that results in the ring-opening of the core with loss of its fluorescence. The various characterization techniques used in this study, such as X-ray diffraction, NMR spectroscopy, mass spectrometry, and UV–vis analysis, warrant accurate identification of the structures of the newly synthesized compounds. DFT studies were also performed in order to understand the mechanism associated with this reaction.
