Dye sd1 synthesis
WebDec 6, 2010 · The synthesis and properties of azo dyes that can be used for photoaligning liquid crystals (LCs) have been investigated. The structures and the synthetic procedure … 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.
