Description

3-Butyl-2-[3-(1,3-Dihydro-1,3,3-Trimethyl-2H-Indol-2-Ylidene)-1-Propen-1-Yl]-1,1-Dimethyl-1H-Benz[E]Indolium Perchlorate is a high-purity, functional organic salt belonging to the cyanine dye family, specifically a heptamethine cyanine derivative. This compound matters for its exceptional optical properties, serving as a critical near-infrared (NIR) absorbing chromophore and photosensitizer. Industrial and research laboratories need it for advanced material development, particularly in the fields of nonlinear optics (NLO), photodynamic therapy (PDT), and as a key intermediate for specialty dyes and sensors.

Application

• Nonlinear Optical (NLO) Materials: A key component in the synthesis of organic materials for optical limiting, frequency conversion, and electro-optic modulation devices.
• Photodynamic Therapy (PDT) Research: Acts as a potent photosensitizer for the development of new cancer treatments and antimicrobial agents due to its strong NIR absorption.
• Laser Dye & Optical Recording Media: Used in the formulation of tunable dye lasers and high-density optical data storage materials.
• Chemical Sensing Probes: Serves as a building block for creating highly sensitive and selective fluorescent or colorimetric sensors for ions and biomolecules.
• Advanced Organic Synthesis: An important intermediate for constructing complex conjugated systems and functional dyes with tailored photophysical properties.
• Solar Cell Research: Investigated as a light-harvesting component in dye-sensitized solar cells (DSSCs) and organic photovoltaics.
