Description

1-Butyl-2-[5-(1-Butyl-1,3-Dihydro-3,3-Dimethyl-2H-Indol-2-Ylidene)-Penta-1,3-Dienyl]-3,3-Dimethyl-3H-Indolium Hexafluorophosphate is a high-purity, functional organic salt belonging to the cyanine dye family, valued for its exceptional photophysical properties. This compound is a critical material for advanced research and development in photonics and optoelectronics, where precise molecular characteristics are paramount. It is primarily sought by manufacturers and R&D laboratories in the fields of nonlinear optics (NLO), optical data storage, and as a sensitizer for photopolymerization and photovoltaic applications.

Application

• Nonlinear Optical (NLO) Materials: A key chromophore for developing organic materials with high second- and third-order nonlinear optical susceptibilities for optical switching and signal processing.
• Optical Data Storage: Used as a photosensitive dye in the formulation of recordable optical media (e.g., CD-R, DVD-R) due to its strong absorption in the visible to near-infrared range.
• Photopolymerization Initiators/Sensitizers: Acts as a highly efficient photoinitiator or co-initiator in UV-curable inks, coatings, adhesives, and 3D printing resins.
• Dye-Sensitized Solar Cells (DSSCs): Investigated as a potential sensitizer to broaden the light absorption spectrum and improve photon-to-electron conversion efficiency.
• Biomedical Imaging and Photodynamic Therapy: Serves as a potential candidate for fluorescence probes or photosensitizers due to its tunable absorption and emission profiles.
• Laser Dyes and Optical Filters: Utilized in the tuning of dye lasers and in the manufacturing of specific optical filters for scientific and industrial equipment.
