Abd El-Aal, Reda Mahmoud published the artcileSynthesis and characterization of new photosensitizer bridgehead cyanine dyes, Synthetic Route of 606-55-3, the publication is Proceedings – Indian Academy of Sciences, Chemical Sciences (1999), 111(2), 343-352, database is CAplus.
Oxazolo[1,2-a]quinoline derivatives were used to synthesize novel bridgehead cyanine dyes such as azamethine, monomethine, and trimethine cyanines. The electronic absorption spectra of these cationic dyes in ethanol and several organic solvents are discussed.
