Fusion of benzene moieties onto the BODIPY periphery in combination with the introduction of peripheral chiral binaphthyl substituents renders the extension of optical activity of resulting chiral benzo-fused aza-BODIPYs into the near-IR (NIR) range, representing the first chiral BODIPYs with NIR optically activity.
