Description

1,1,2,2-Tetrakis(4-(2-(Trimethylsilyl)Ethynyl)Phenyl)Ethene is a highly functionalized organic semiconductor material belonging to the tetraphenylethene (TPE) family, renowned for its aggregation-induced emission (AIE) properties. This compound is engineered for advanced applications in optoelectronics and materials science, where precise molecular architecture and luminescent behavior are critical. It serves as a key building block for researchers and manufacturers in organic light-emitting diodes (OLEDs), chemical sensors, and advanced photonic materials.

Application

• OLED Emitters & Host Materials: A core component in the development of non-doped, high-efficiency blue or deep-blue organic light-emitting diodes (OLEDs) for displays and solid-state lighting.
• AIE-based Chemical Sensors: Utilized as a sensitive fluorophore in the fabrication of sensors for detecting explosives, volatile organic compounds (VOCs), metal ions, and specific biomolecules due to its "turn-on" emission in aggregated states.
• Advanced Photoresists & Lithography: Serves as a functional monomer or cross-linker in photosensitive resins for high-resolution patterning in microelectronics and nanotechnology.
• Luminescent Probes & Bioimaging: Employed in the design of biocompatible probes for cellular imaging and tracking, leveraging its AIE characteristics for high signal-to-noise ratio in aqueous environments.
• Organic Field-Effect Transistors (OFETs): Acts as an active layer material due to its extended π-conjugation and potential for charge carrier mobility.
• Security Inks & Anti-Counterfeiting Tags: Incorporated into inks and tags that exhibit distinct fluorescence under UV light, used for document security and brand protection.
