Description

2-[(E)-2-(2-Chloro-3-((E)-2-[3-Ethyl-5-Phenyl-1,3-Benzoxazol-2(3H)-Ylidene]Ethylidene)-1-Cyclopenten-1-Yl)Ethenyl]-3-Ethyl-5-Phenyl-1,3-Benzoxazol-3-Ium Iodide is a high-purity, specialized organic salt belonging to the cyanine dye family, valued for its exceptional photophysical properties. This compound serves as a critical functional material in advanced optical and electronic applications where precise light absorption and emission characteristics are paramount. It is primarily sought by manufacturers and research institutions in the fields of nonlinear optics (NLO), photovoltaics, and as a sensitizing dye for photographic emulsions and imaging technologies.

Application

• Nonlinear Optical (NLO) Materials: A key chromophore for developing advanced materials used in optical limiting, frequency doubling, and electro-optic modulation devices.
• Dye-Sensitized Solar Cells (DSSCs): Functions as a sensitizer to absorb a broad spectrum of light and facilitate electron injection into semiconductor electrodes.
• Photographic Sensitizers: Used in the formulation of specialized photographic emulsions to extend spectral sensitivity into specific wavelength ranges.
• Laser Dyes and Optical Filters: Employed in the tuning of laser systems and the manufacture of high-performance optical filters due to its sharp absorption bands.
• Organic Photoconductors (OPCs): A component in photoreceptor layers for photocopiers and laser printers.
• Biomedical Imaging Probes: Potential use in the development of fluorescent markers and probes for cellular imaging, subject to further biocompatibility formulation.
• Academic and Industrial R&D: Serves as a building block or reference standard for research in organic synthesis, photochemistry, and material science.
