Description

3-Hexadecyl-2-[3-(3-Hexadecyl-2(3H)-Benzoxazolylidene)-1-Propenyl]Benzoxazolium, Iodide is a specialized cationic cyanine dye belonging to the benzoxazole family, valued for its strong near-infrared (NIR) absorption and fluorescence properties. This compound is engineered for high-performance applications where precise light interaction and signal generation are critical. It is primarily sought by researchers and manufacturers in the fields of advanced materials science, optical recording, and as a key component in the synthesis of functional dyes and photosensitizers.

Application

• Optical Data Storage: As a functional dye layer in recordable (R) and rewritable (RW) optical discs (e.g., CD-R, DVD±R) for laser writing and reading.
• Non-Linear Optical (NLO) Materials: A key chromophore for developing materials with second- and third-order optical non-linearity for photonic devices.
• Laser Dye & Photonics: Potential use as a gain medium or saturable absorber in tunable dye lasers and optical switches due to its specific absorption/emission profile.
• Biomedical Imaging & Sensing: As a precursor or core structure for synthesizing NIR-fluorescent probes and labels for bioassays and cellular imaging.
• Organic Photovoltaics (OPV) & Solar Cells: As an electron donor or acceptor material in the active layer to enhance light-harvesting efficiency.
• Chemical Sensing: Development of selective chemosensors where its fluorescence properties change upon binding with specific ions or molecules.
