Description

1,1,3-Trimethyl-2-(7-(1,1,3-Trimethyl-1H-2(3H)-Benz Indolidene)-1,3,5- Heptatrienyl)-1H-Benz Indolium Iodide is a high-purity, synthetic organic salt belonging to the cyanine dye family, recognized for its distinct photophysical properties. This compound is valued for its role as a key intermediate and functional dye in advanced research and specialty manufacturing. It is primarily sought by R&D laboratories and industrial producers in the photographic, optical data storage, and non-linear optics (NLO) sectors.

Application

• Optical Data Storage Media: As a functional dye layer in recordable (CD-R, DVD-R) and high-density optical discs.
• Photographic Sensitizers: Used in the formulation of specialized photographic emulsions and films.
• Non-Linear Optical (NLO) Materials: A key chromophore for research and development of materials for frequency doubling, optical switching, and laser applications.
• Laser Dyes: Potential use as a gain medium in tunable dye lasers for specific wavelength ranges.
• Biomedical Imaging Probes: Investigated for use as a fluorescent label or marker in cellular and molecular imaging due to its cyanine backbone.
• Organic Photovoltaic (OPV) Research: Employed in the development of light-absorbing layers for solar cell applications.
• Chemical Synthesis: Serves as a sophisticated intermediate for synthesizing more complex cyanine dyes and related heterocyclic compounds.
