(E)-2,6-Di­bromo-4-{2-[1-(1H,1H,2H,2H-perfluoro­oct­yl)pyridinium-4-yl]ethen­yl}phenolate methanol disolvate, a fluoro­ponytailed solvatochromic dye

The title compound, C(21)H(12)Br(2)F(13)NO·2CH(3)OH, was obtained by condensation of 4-methyl-1-(1H,1H,2H,2H-perfluoro­oct­yl)pyridinium iodide and 3,5-di­bromo-4-hy­droxy­benzaldehyde, followed by deprotonation. It crystallizes as a methanol disolvate and exhibits short O—H⋯O hydrogen bonds and a d...

Sumario:The title compound, C(21)H(12)Br(2)F(13)NO·2CH(3)OH, was obtained by condensation of 4-methyl-1-(1H,1H,2H,2H-perfluoro­oct­yl)pyridinium iodide and 3,5-di­bromo-4-hy­droxy­benzaldehyde, followed by deprotonation. It crystallizes as a methanol disolvate and exhibits short O—H⋯O hydrogen bonds and a disordered perfluoro­alkyl chain [occupancy ratio 0.538 (7):0.462 (7)]. Significant π–π stacking inter­actions are observed between the benzene and pyridine rings of neighbouring mol­ecules along the b-axis direction.
