Description

1,3,3-Trimethyl-2-[(E)-3-(1,3,3-Trimethyl-1,3-Dihydro-2H-Indol-2-Ylidene)-1-Propenyl]-3H-Indolium Tetraphenylborate is a high-purity, functional organic salt belonging to the cyanine dye family, specifically a heptamethine cyanine with a tetraphenylborate counterion. This compound matters for its exceptional photophysical properties, serving as a critical functional material and advanced synthetic intermediate. It is primarily needed by manufacturers in the optical materials, specialty dyes, and advanced electronics sectors for applications requiring precise light absorption and emission characteristics.

Application

• Optical Data Storage Media: As a key functional dye for recordable (R) and rewritable (RW) optical discs, including CD-R, DVD-R, and Blu-ray formats.
• Laser and Nonlinear Optical Materials: As an active medium or dopant in solid-state dye lasers and for developing materials with nonlinear optical (NLO) properties.
• Photodynamic Therapy (PDT) Research: As a potential photosensitizer in biomedical research due to its strong absorption in the near-infrared (NIR) region.
• Organic Photovoltaic (OPV) Cells: As an electron donor or acceptor material in the active layer of solar cell research and development.
• Chemical Sensors and Probes: For the development of fluorescent or colorimetric sensors for detecting specific ions or biomolecules.
• Specialty Inks and Coatings: In formulations for security printing, authentication markers, or high-performance pigments.
• Academic and Industrial R&D: As a building block for synthesizing more complex cyanine dyes and functional organic molecules.
