A series of BODIPYs (boron-dipyrromethene dyes; 4,4-difluoro-5-aryl-4-bora-3a, 4a-diaza-s-indacene) derivatives, bearing an aldehyde group at different pyrrole positions, were transformed into gem-dibromovinyl analogs using the Corey-Fuchs or Lautens olefination method. The gem-dibromovinyl moieties (one or two) are symmetric/asymmetric and attached at α- or β-positions of the pyrrole ring, directly or through the extension of a β-position substituted phenyl spacer ring. The molecular structures of the resultant dyes were assigned using MS, ¹H, ¹³C, ¹⁹F NMR, X-ray diffraction and for some compounds 2D HSQC and ¹¹B NMR. The absorption, fluorescence and solvatochromism properties were investigated in different solvents. The highest absorption and emission maxima were obtained for compounds having two gem-dibromovinyl groups attached directly at the α-positions. The best correlation (R-coefficient) of absorption between the solvents and spectral properties of the BODIPYs was obtained using the refractive index of the solvent. The R-coefficient of emission was obtained only for compounds having gem-dibromo vinyl moieties at α-positions. Their solid states clearly reveal distinct patterns of gem-dibromovinyl orientation, torsion angles of the 5-phenyl ring and the indacene plane. Hirshfeld surface analysis were used to visualize various intermolecular interactions.
