Cyanine Dyes, Squarylium Dyes (23)

Cyanine and squaraine dyes are organic pigments characterized by their intense absorption and emission in the visible and near-infrared regions. Renowned for their high extinction coefficients and photostability, these dyes are widely utilized in imaging and sensing applications, including near-infrared spectroscopy, bioimaging, and solar cells. Their exceptional optical properties render them indispensable for detecting and visualizing biological structures and processes.
