Five novel polyaromatic-ring-fused bisBODIPYs have been synthesized from corresponding readily available α-arylBODIPYs through a FeCl3-mediated tandem inter- and intramolecular oxidative aromatic coupling reaction. These resultant show twisted planar conformations, strong absorptions (ε up to 1.8 × 105 M-1 cm-1), good fluorescence emissions in the near-infrared region (NIR, 660-734 nm) intersystem crossing efficiencies (ΦΔ = 18.9% for dimer 2d toluene), demonstrating their promising potential applications as heavy-atom-free photosensitizers.
