Description

2-[3-(1,3-Dihydro-1,3,3-Trimethyl-2H-Indol-2-Ylidene)Prop-1-Enyl]-1,3,3-Trimethyl-3H-Indolium Formate is a high-purity cyanine dye salt, valued for its strong near-infrared (NIR) absorption and fluorescence properties. This compound is essential for applications requiring precise light absorption and emission in the NIR spectrum, offering excellent photostability and solubility. It is primarily needed by manufacturers and researchers in the fields of optical data storage, biomedical imaging, and advanced material science.

Application

• Optical Data Storage Media: A key component in the formulation of recordable (R) and rewritable (RW) optical discs (e.g., CD-R, DVD-R) as a light-absorbing layer.
• Biomedical Imaging & Diagnostics: Used as a fluorescent probe or tag in NIR fluorescence imaging for deep-tissue analysis and diagnostic assays.
• Laser Technology & Photonics: Serves as a gain medium or saturable absorber in tunable dye lasers and other photonic devices operating in the NIR region.
• Non-Linear Optical Materials: Incorporated into polymers and crystals for applications in optical limiting, switching, and frequency conversion.
• Security Inks & Dyes: Utilized in anti-counterfeiting inks and security markings due to its specific and detectable NIR signature.
• Solar Energy & Photovoltaics: Investigated for use in dye-sensitized solar cells (DSSCs) and organic photovoltaics as a light-harvesting sensitizer.
• Academic & Industrial Research: A critical reagent for spectroscopic studies, material science research, and the development of new optoelectronic applications.
