To dye for : A highly fluorescent, photostable aza‐dipyrromethene dye 1 ( λ em =751 nm) with sharp and intense absorption (full width at half maximum height=30.4 nm; ε =159 000) in the near‐infrared (NIR) region ( λ max =740 nm) is reported. The dye is insensitive to solvent polarity, meets the requirements of a NIR chromophore, and has potential use in biological probes.
