New biscyanine dye based on 1-{2-oxo-2-[4-(2-oxo-2H-chromen-3-yl)phenyl]ethyl}-4-methylpyridinium bromide. Electron transitions and electronic spectra

New biscyanine dye, 4-{2-[4-(dimethylamino)phenyl]ethenyl}-1-{2-[4-(dimethylamino)phenyl]-1-[4-(2-oxo-2H-chromen-3-yl)benzoyl]ethenyl}pyridinium bromide, has been prepared via condensation of 4-dimethylaminobenzaldehyde with 4-methyl-1-{2-oxo-2-[4-(2-oxo-2H-chromen-3-yl)phenyl]ethyl}pyridinium bromide. The latter has been synthesized via the Meerwein reaction of coumarin with 4-acetylphenyldiazonium chloride with subsequent bromination and quaternization of the formed α-bromoketone under the action of 4-methylpyridine. Electronic spectra are analyzed, and quantum-chemical simulation of possible isomers of the biscyanine dye has been performed.
