Description

1,1'-Diethyl-2,2'-Carbocyanine Iodide is a vital cyanine dye salt widely recognized for its strong near-infrared (NIR) absorption and fluorescence properties. This compound is essential for researchers and manufacturers requiring precise optical characteristics in advanced material systems. It is primarily utilized in the development of optical recording media, laser dyes, and as a sensitizer in photographic emulsions. Industries involved in photonics, imaging technology, and specialty chemical synthesis rely on its consistent performance and high purity.

Application

• Optical Data Storage: A key component in the formulation of recordable optical discs (CD-R, DVD-R) and other NIR-sensitive media.
• Laser Technology: Employed as a gain medium or saturable absorber in tunable dye lasers operating in the near-infrared spectrum.
• Photographic Sensitization: Acts as a spectral sensitizer for silver halide photographic emulsions, extending their sensitivity into longer wavelengths.
• Nonlinear Optics (NLO): Used in research and development of materials for optical limiting, switching, and frequency conversion due to its large nonlinear optical coefficients.
• Biomedical Imaging Probes: Serves as a foundational structure for synthesizing NIR fluorescent labels and probes for in vitro diagnostics and research.
• Organic Photovoltaic (OPV) Research: Investigated as an electron donor or acceptor material in the active layer of solar cells for its light-harvesting properties.
