Аннотация:Coumarin-fused BODIPY dye was designed and synthesized. Convenient method for synthesis of 2-benzoylchromeno[4,3-b]pyrrol-4(1H)-one from 7-diethylamino-3-formylcoumarine was developed. Coumarin-fused BODIPY dye showed intensive near-IR fluorescence (maximum at 748 nm) and unusually high Stokes shift in polar solvent (142 nm).
