Description

1,2,4,5-Tetrakis(4-Cyanophenyl)Benzene is a high-purity, multi-functional organic building block characterized by its rigid, star-shaped molecular architecture with four peripheral cyano groups. This compound matters for its exceptional utility as a precursor in the synthesis of advanced porous organic polymers (POPs), covalent organic frameworks (COFs), and other functional materials. It is critically needed by researchers and manufacturers in the fields of gas storage, heterogeneous catalysis, and optoelectronic device development, where precise molecular control is paramount.

Application

• Porous Material Synthesis: A key monomer for constructing high-surface-area Covalent Organic Frameworks (COFs) and Porous Aromatic Frameworks (PAFs) for gas (H₂, CO₂, CH₄) adsorption and separation.
• Heterogeneous Catalysis: Serves as a robust, functional scaffold for immobilizing metal catalysts, enhancing recyclability and activity in various organic transformations.
• Optoelectronic Devices: Used as an electron-deficient building block in the development of organic semiconductors, light-emitting diodes (OLEDs), and photovoltaic materials.
• Chemical Sensing: Incorporated into fluorescent sensors and detection platforms due to its tunable photophysical properties upon interaction with analytes.
• Advanced Composites: Acts as a cross-linking agent or reinforcing unit in high-performance polymers and composites to improve thermal and mechanical stability.
• Academic & Industrial R&D: A fundamental reagent for exploratory research in supramolecular chemistry, nanotechnology, and material science.
