Description

2-(2-[(E)-2-(3-Ethyl-1,3-Benzothiazol-3-Ium-2-Yl)Ethenyl]-5-((E)-2-[3-Ethyl-1,3-Benzothiazol-2(3H)-Ylidene]Ethylidene)-1-Cyclopenten-1-Yl)-1-Oxo-1H-Inden-3-Olate is a sophisticated cyanine dye derivative, valued for its strong near-infrared (NIR) absorption and fluorescence properties. This compound is engineered for applications requiring high-performance optical characteristics, such as photostability and tunable emission. It is a critical material for researchers and manufacturers in the fields of optical data storage, laser technology, and advanced biomedical imaging.

Application

• Optical Data Storage Media: Used as a light-absorbing layer in recordable (R) and rewritable (RW) CDs, DVDs, and Blu-ray discs.
• Laser Dyes and Optical Filters: Serves as an active medium in tunable dye lasers and as a component in NIR optical filters and shutters.
• Non-Linear Optical (NLO) Materials: Incorporated into polymers and crystals for applications in photonics, including optical switching and signal modulation.
• Biomedical Imaging Probes: Utilized in the development of contrast agents and fluorescent labels for deep-tissue imaging and diagnostic assays.
• Solar Energy and Photovoltaics: Investigated as a photosensitizer in dye-sensitized solar cells (DSSCs) due to its broad light absorption.
• Security Inks and Dyes: Employed in anti-counterfeiting inks for banknotes, documents, and high-value products due to its specific spectral signature.
