WebThe xanthene dyes synthesized in this experiment all are sufficiently conjugated to absorb in the visible range of the spectrum provided they are in a form where the central carbon between all three aromatic rings is sp2 hybridized. This allows conjugation between the different aromatic rings. We can see this if we consider the dye fluorescein. WebSometime between 1858 and 1859, French chemist François-Emmanuel Verguin found that reaction of aniline with stannic chloride gave a fuchsia, or rose-coloured, dye, which he named fuchsine. It was the first of the triphenylmethane dyes and triggered the second phase of the synthetic dye industry.
