Synthesis and properties of water-soluble 1,9-dialkyl-substituted BF

Dan Wu, Gonzalo Durán-Sampedro, Donal F. O’Shea

Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 1,   Pages 97-104 doi: 10.1007/s11705-019-1828-x

Abstract: Bis-alkylsulfonic acid and polyethylene glycol (PEG)-substituted BF azadipyrromethenes have been synthesized by an adaptable and versatile route. Only four synthetic stages were required to produce the penultimate fluorophore compounds, containing either two alcohol or two terminal alkyne substituents. The final synthetic step introduced either sulfonic acid or polyethylene glycol groups to impart aqueous solubility. Sulfonic acid groups were introduced by reaction of the bis-alcohol-substituted fluorophore with sulfur trioxide, and a double Cu(I)-catalyzed cycloaddition reaction between the bis-alkyne fluorophore and methoxypolyethylene glycol azide yielded a neutral bis-pegylated derivative. Both fluorophores exhibited excellent near-infrared (NIR) photophysical properties in methanol and aqueous solutions. Live cell microscopy imaging revealed efficient uptake and intracellular labelling of cells for both fluorophores. Their simple synthesis, with potential for last-step structural modifications, makes the present NIR-active azadipyrromethene derivatives potentially useful as NIR fluorescence imaging probes for live cells.
