Description

Tetra-(4-Pyridylphenyl)Ethylene (CAS NO 1227195-24-5) is a highly functionalized organic compound featuring a tetraphenylethylene (TPE) core substituted with four pyridylphenyl arms. This molecular architecture is significant for its aggregation-induced emission (AIE) properties, making it a valuable building block in advanced materials science. It is primarily needed by researchers and manufacturers in the fields of organic electronics, chemical sensing, and luminescent materials development.

Application

• As a key AIE luminogen (AIEgen) for the development of solid-state luminescent materials and films.
• As a functional monomer or cross-linker in the synthesis of porous organic polymers (POPs) and metal-organic frameworks (MOFs) for gas storage or separation.
• In the fabrication of chemo-sensors and bio-sensors for the detection of explosives, volatile organic compounds (VOCs), or specific ions.
• As an electron-transport or host material in the research and development of organic light-emitting diodes (OLEDs).
• For the creation of stimuli-responsive smart materials used in data encryption, anti-counterfeiting, and optoelectronic devices.
• In academic and industrial R&D as a versatile molecular scaffold for exploring structure-property relationships in photophysics.
