Examples

• Cyanine dyes are widely used in infrared photography and fluorescence microscopy.
• The photographer selected cyanine film for its enhanced sensitivity to red light.
• Cyanine compounds exhibit strong absorption in the near-infrared region of the spectrum.
• Textile manufacturers apply cyanine dyes to achieve vibrant blue and green colors.
• The cyanine structure allows for tunable optical properties by modifying the conjugated chain.
