Palladium Catalyzed, Annulative Multiple C‐H Bond Activations of BODIPYs to Access π‐Extended Polycyclic Heteroaromatic Molecules with Deep Red Emissions and S elf ‐ aggregation Behaviors
Aromatic ring fusion on BODIPY core can effectively tune its electronic property, and red‐shift its absorption and emission wavelength. In this work, we report that a one‐pot Pd(II) catalyzed multiple C−H activation to access acenaphtho[ b ]‐fused BODIPYs though the reaction of α , β ‐unsubstituted‐...

description | Aromatic ring fusion on BODIPY core can effectively tune its electronic property, and red‐shift its absorption and emission wavelength. In this work, we report that a one‐pot Pd(II) catalyzed multiple C−H activation to access acenaphtho[

,
β
‐unsubstituted‐BODIPYs and 1,8‐dibromonaphthalenes. These newly synthesized acenaphtho[
b
]‐fused BODIPYs revealed intensified deep red absorptions (639–669 nm) and emissions (643–683 nm), with high fluorescence quantum yields (0.53–0.84) in dichloromethane. Notably, these acenaphtho[
b
]‐fused BODIPYs exhibited well‐defined self‐aggregation behavior in water/THF mixture, and for instance, the absorption of

was red‐shifted by 53 nm to 693 nm after forming aggregates. |
