Description

1,2,4,5-Tetracyanobenzene (CAS NO 712-74-3) is a highly functionalized aromatic compound characterized by four cyano groups symmetrically arranged on a benzene ring. This unique structure makes it a valuable multifunctional building block and precursor for advanced materials synthesis. It is primarily sought after by research institutions and specialty chemical manufacturers developing high-performance polymers, organic semiconductors, and metal-organic frameworks (MOFs).

Application

• Organic Semiconductor Precursor: Serves as a key monomer for synthesizing n-type organic semiconductors and conductive polymers used in OLEDs, OFETs, and photovoltaic cells.
• Metal-Organic Framework (MOF) Synthesis: Acts as a versatile organic linker due to its multiple cyano groups, enabling the construction of porous coordination polymers with high surface areas for gas storage and catalysis.
• High-Performance Polymer Intermediate: Used in the production of polyimides, polyamides, and other heat-resistant polymers where the rigid, aromatic core enhances thermal and mechanical stability.
• Ligand in Coordination Chemistry: Functions as a polydentate ligand for forming complexes with various metal ions, useful in catalysis and materials science.
• Chemical Research & Development: Employed in academic and industrial R&D for exploring novel organic reactions and creating new molecular architectures.
• Dye and Pigment Intermediate: Can be utilized in the synthesis of specialized phthalocyanine-type dyes and pigments.
