Features And Benefits
Cyanine dyes contain some N-heterocycles on both sides of the polymethine structure. The N-heterocycle on the one side is a cationic ammonium with an electron-withdrawing effect, and the other N-heterocycle is a tertiary amine with an electron-donating effect. Accordingly, cyanine dyes show the light absorption of a charge transfer through the central polymethine structure.
