Description

3-Butyl-2-[3-(3-Butyl-1,3-Dihydro-1,1-Dimethyl-2H-Benz[E]Indol-2-Ylidene)-1-Propen-1-Yl]-1,1-Dimethyl-1H-Benz[E]Indolium Iodide is a high-purity, functional organic salt belonging to the cyanine dye family, valued for its strong near-infrared (NIR) absorption and fluorescence properties. This compound is critical for advanced research and development in photonics and materials science, where precise optical characteristics are required. It is primarily sought by manufacturers and researchers in the fields of optical data storage, laser technology, and as a key sensitizer for dye-sensitized solar cells (DSSCs).

Application

• NIR-Absorbing Dye for Optical Data Storage Media: Used as a recording layer material in writable and rewritable optical discs (e.g., CD-R, DVD-R).
• Photosensitizer for Dye-Sensitized Solar Cells (DSSCs): Enhances light-harvesting efficiency in the near-infrared spectrum for next-generation photovoltaic devices.
• Laser Dye and Optical Limiting Materials: Employed in the formulation of tunable liquid lasers and for developing optical limiters that protect sensors from intense light.
• Biomedical Imaging Probes: Serves as a precursor for synthesizing fluorescent labels and contrast agents used in in-vivo imaging and diagnostics.
• Non-Linear Optical (NLO) Materials: A key component in the research and production of materials for frequency doubling and electro-optic modulation.
• Photodynamic Therapy (PDT) Research: Investigated for its potential as a photosensitizing agent in targeted cancer therapies.
