The field of porous materials has been revolutionized by the advent of Metal-Organic Frameworks (MOFs) and Covalent Organic Frameworks (COFs). At NINGBO INNO PHARMCHEM CO.,LTD., we are deeply involved in providing the essential building blocks for these advanced materials, with Tris(4-ethynylphenyl)amine (CAS 189178-09-4) being a prime example as a versatile ligand.

MOFs and COFs are crystalline materials constructed from molecular building blocks, creating highly porous structures with exceptionally high surface areas. The properties of these frameworks are dictated by the choice of organic ligands and metal nodes (in MOFs) or organic linkers (in COFs). Tris(4-ethynylphenyl)amine excels as an organic linker or ligand due to its trifunctional nature, allowing for the formation of robust, three-dimensional networks through covalent bond formation or coordination.

The ethynyl groups on Tris(4-ethynylphenyl)amine are particularly advantageous for COF synthesis. These terminal alkynes readily participate in various polymerization reactions, such as the Sonogashira coupling with dihaloarenes or click polymerization reactions. The resulting COFs often exhibit exceptional thermal stability and chemical resistance, along with precisely tunable pore sizes. This tunability is critical for applications like selective gas adsorption, catalysis, and molecular separations, where the pore environment must be carefully controlled.

In the context of MOFs, while Tris(4-ethynylphenyl)amine might not directly coordinate to metal ions as a typical carboxylate or imidazole ligand, its ethynyl groups can be further functionalized or used in post-synthetic modification to introduce desired properties. Alternatively, its structure can serve as a template or component in the synthesis of functionalized ligands that are then incorporated into MOFs.

The ethynylphenyl amine chemical structure provides a rigid and well-defined geometry, which is crucial for predictable framework assembly and the creation of ordered pores. The ability to design frameworks with specific pore sizes and surface chemistries using ligands like Tris(4-ethynylphenyl)amine is driving innovation across multiple industries, from energy storage to environmental remediation. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing the high-quality Tris(4-ethynylphenyl)amine necessary to realize the full potential of these advanced porous materials.
