Description

1,3,3-Trimethyl-2-((E)-2-(2-(1-naphthyl)-3-[(E)-2-(1,3,3-trimethyl-1,3-dihydro-2H-indol-2-ylidene)ethylidene]-1-cyclopenten-1-yl)ethenyl)-3H-indolium tetrafluoroborate is a high-purity, synthetic cyanine dye salt, a critical functional material in advanced photonic and electronic applications. Its value lies in its exceptional light-absorption and emission properties, which are precisely tunable due to its complex polymethine structure. This compound is essential for research and development teams in the optical data storage, nonlinear optics (NLO), and laser dye sectors, where precise molecular engineering is paramount for performance.

Application

• Optical Data Storage Media: A key functional dye for recordable (R) and rewritable (RW) optical discs (e.g., CD-R, DVD±R).
• Nonlinear Optical (NLO) Materials: Used in the development of materials for optical limiting, frequency doubling, and electro-optic modulation devices.
• Laser Dye Precursor: Serves as an active medium or sensitizer in tunable dye lasers across specific wavelength ranges.
• Photodynamic Therapy (PDT) Research: Investigated as a potential photosensitizer due to its strong light absorption characteristics.
• Organic Photovoltaic (OPV) & OLED Research: Used in academic and industrial R&D for developing light-harvesting or emissive layers.
• Chemical Sensors: Employed in the fabrication of optochemical sensors where its spectral properties change upon analyte interaction.
• High-Resolution Imaging: Potential application as a contrast agent or fluorescent marker in specialized bioimaging techniques.
