ABSTRACT
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,ß-unsubstituted-BODIPYs and 1,8-dibromonaphthalenes. These newly synthesized acenaphtho[b]-fused BODIPYs revealed intensified deep red absorptions (639-669â
nm) and emissions (643-683â
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 3 a was red-shifted by 53â
nm to 693â
nm after forming aggregates.
