Description

11-Dimethylamino-3,3'-Diethyl-10,12-Ethylenethiatricarbocyanine Perchlorate is a specialized cyanine dye salt, a member of the polymethine class, recognized for its distinct photophysical properties. This compound is valued for its strong near-infrared (NIR) absorption and fluorescence, making it a critical functional material in advanced research and technology sectors. It is primarily sought by professionals in photovoltaics, optical data storage, and biomedical imaging for its role as a sensitizer and probe.

Application

• Optical Data Storage: Used as a light-absorbing layer in recordable (R) and rewritable (RW) optical discs (e.g., CD-R, DVD-R).
• Dye-Sensitized Solar Cells (DSSCs): Functions as a photosensitizer to absorb light and initiate electron transfer processes.
• Non-Linear Optics (NLO): Employed in the development of materials for optical limiting, switching, and frequency conversion.
• Biomedical Imaging & Photodynamic Therapy (PDT): Serves as a NIR fluorescent probe or photosensitizer for diagnostic imaging and targeted light-activated treatments.
• Laser Technology: Acts as a gain medium or saturable absorber in tunable dye lasers operating in the NIR spectrum.
• Photopolymerization & Photoresists: Utilized as a photoinitiator or sensitizer in UV-curable coatings, inks, and microelectronics patterning.

Quality Control

Our production of this high-purity functional dye adheres to stringent quality protocols. Every batch is characterized using advanced analytical techniques including HPLC, NMR, and UV-Vis-NIR spectroscopy to confirm identity, purity, and optical performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and spectral data is provided with each shipment to ensure consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive nature and perchlorate content, the container should be kept in a dedicated, well-ventilated area away from incompatible materials such as strong reducing agents and combustible substances.
