Term Name: cyanine dye
Synonyms: cyanine dyes, Cyaninfarbstoff, Zyaninfarbstoff
Definition: Cyanine dyes are synthetic dyes with the general formula R2N[CH=CH]nCH=N+R2 ↔ R2N+=CH[CH=CH]nNR2 (n is a small number) in which the nitrogen and part of the conjugated chain usually form part of a heterocyclic system, such as imidazole, pyridine, pyrrole, quinoline and thiazole.
