New soluble dyes and insoluble organic pigments based on the diketopyrrolopyrrole skeleton have been prepared via Suzuki–Miyaura coupling on 3,6-bis(4-bromophenyl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione. Boc protection of the amidic functions was advantageously used to solubilize the starting diketopyrrolopyrrole prior to the introduction of substituents. Absorption, fluorescence emission and optical features of these new diketopyrrolopyrroles dyes are presented.
