Pyrrolopyrrole cyanine dyes: A new class of near-Infrared dyes and fluorophores
Pyrrolopyrrole cyanine (PPCy) dyes are presented as a novel class of near-infrared (NIR) chromophores, which are synthesized in a condensation reaction of diketopyrrolopyr-role with heteroarylacetonitrile compounds. Their optical properties are marked by strong and narrow-band NIR absorptions. Complexation prod-ucts with BF2 and BPh2 show strong NIR fluorescence and hardly any ab-sorption in the visible range. We syn-thesized a series of new PPCys that differ only in the heterocyclic peripheral groups of the chromophore. With this strategy, the absorption spectra can be tuned between 684 and 864 nm, while high fluorescence quantum yields are maintained. The influence of the heterocycle on the optical properties of the dyes is discussed.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C8H5ClN2, you can also check out more blogs about1448-87-9
