Description

4-(Dicyanomethylene)-2-tert-Butyl-6-(1,1,7,7-Tetramethyljulolidin-4-Yl-Vinyl)-4H-Pyran is a high-performance organic dye and functional material known for its exceptional photophysical properties. This compound matters for its strong near-infrared (NIR) absorption and emission characteristics, making it a critical component in advanced optical applications. It is primarily needed by manufacturers and researchers in the photovoltaic, laser technology, and optical data storage industries, as well as for developing non-linear optical (NLO) materials and bio-imaging probes.

Application

• Laser Dye Medium: Used as a gain medium in tunable dye lasers, particularly for operations in the near-infrared spectral region.
• Organic Photovoltaic (OPV) Cells: Functions as an electron acceptor or sensitizer to enhance light absorption and charge generation in solar cell devices.
• Non-Linear Optical (NLO) Materials: A key chromophore for fabricating materials with high second- or third-order optical non-linearity for frequency conversion and optical switching.
• Optical Data Storage: Employed in the development of advanced write-once or rewritable optical discs due to its specific light-absorption properties.
• Bio-imaging and Sensing: Serves as a fluorescent probe for deep-tissue imaging in the NIR window, where biological tissues have minimal absorption and autofluorescence.
• Photodynamic Therapy (PDT) Research: Investigated as a potential photosensitizer for targeted cancer treatments.
• Optical Limiting Devices: Used in materials designed to protect sensitive optical sensors and human eyes from intense laser pulses.
• Academic and Industrial R&D: A fundamental building block for synthesizing novel π-conjugated systems and studying structure-property relationships in functional dyes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive nature and tendency to be easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat and incompatible materials.
