Cyanine Dyes
Cyanine Dyes(花青染料)
Cyanine dyes are molecules containing polymethine bridge between two nitrogen atoms with a delocalized charge.
Due to their structure, cyanines have outstandingly high extinction coefficients often exceeding 100,000 Lmol-1cm-1. Different substituents allow to control properties of the chromophore, such as absorbance wavelength, photostability, and fluorescence. For example, absorbance and fluorescence wavelength can be controlled by a choice of polymethine bridge length: longer cyanines possess higher absorbance and emission wavelengths up to near infrared region.
