NIRer there: Pyrrolopyrrolecyanine (PPCys) dyes, a new class of near‐infrared (NIR) fluorophores, are obtained by condensation of heteroarylacetonitrile and diketopyrrolopyrrole compounds (see picture). Complexation with BF2 or BPh2 yields strongly fluorescent, photostable NIR dyes that show high absorption cross‐sections and fluorescence quantum yields. Furthermore, alteration of the heterocycle

By a stepwise synthesis strategy biofunctionalized PyrrolopyrroleCyanines (PPCy) with an asymmetric substitution pattern were obtained. These exhibit extremely strong and narrowband NIR absorption and fluorescence. Internalization of a peptide bound PPCy is demonstrated using live cell microscopy.

To tune their opticalproperties, a large variety of pyrrolopyrrolecyanines (PPCys) were synthesized with substituted heteroaromatics such as quinoline, benzothiazole, and ox-azole derivatives as terminal groups. Thus, a broad range of stable, highly fluorescing near-infrared (NIR) dyes with high absorptivities between 690 to 845 nm is accessible. The large number of newly synthesized compounds allows
Pyrrolopyrrole aza-BODIPY analogues were synthesized from diketopyrrolopyrrole and heteroaromatic amines in the presence of titanium tetrachloride. These novel compounds exhibit intense absorption in the visible region and strong emission with high fluorescence quantum yields greater than 0.8.
