Description

1-Butyl-2-[2-[3-[(1-Butyl-6-Chlorobenz[Cd]Indol-2(1H)-Ylidene)Ethylidene]-2-Chloro-1-Cyclohexen-1-Yl]Ethenyl]-6-Chlorobenz[Cd]Indolium Tetrafluoroborate is a specialized near-infrared (NIR) absorbing cyanine dye salt, valued for its exceptional photostability and sharp absorption profile. This compound is critical for advanced applications requiring precise light absorption and energy transfer in the NIR spectrum. It is primarily sought by manufacturers and researchers in the optical data storage, laser technology, and non-linear optical materials sectors.

Application

• Optical Data Storage Media: As a key NIR-absorbing dye for high-density recordable (R) and rewritable (RW) optical discs, including Blu-ray and advanced archival formats.
• Laser and Photonics: An active medium or saturable absorber in tunable dye lasers and for mode-locking in solid-state lasers operating in the near-infrared region.
• Non-Linear Optical (NLO) Materials: A chromophore for developing organic NLO materials used in optical switching, modulation, and frequency conversion devices.
• Photodynamic Therapy (PDT) Research: Investigated as a potential photosensitizer candidate due to its strong NIR absorption, which allows for deeper tissue penetration.
• Security Inks and Dyes: Utilized in covert marking, anti-counterfeiting inks, and security threads for banknotes and high-value documents.
• Solar Energy Research: As a light-harvesting component in the research and development of next-generation organic photovoltaic (OPV) cells and dye-sensitized solar cells (DSSCs).
• Biomedical Imaging: Used in the synthesis of NIR fluorescent probes and contrast agents for in vitro and in vivo imaging applications.
