Abstract:
Spiro-BODIPYs with a diaryl chelate unit have been found to form J-aggregates in methanol-water solvent mixture and brightly emissive in the solid state. The diaryl chelate unit has a significant impact on J-aggregates and fluorescence of BODIPYs. Crystal structural analysis reveals that the spiro-structures facilitate J-stacking in the solid state.
