Description

1,3,5-Tris(4-Ethynylphenyl)Benzene is a high-purity, multi-functional organic building block characterized by its rigid, star-shaped molecular architecture with three terminal alkyne groups. This compound matters for its exceptional utility as a key precursor in advanced materials science, enabling the synthesis of complex, cross-linked networks and porous frameworks. It is primarily needed by researchers and manufacturers in the fields of organic electronics, metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and polymer chemistry for developing next-generation functional materials.

Application

• Covalent Organic Framework (COF) Synthesis: Serves as a crucial three-armed linker for constructing highly porous, crystalline 2D or 3D COF structures with tailored pore sizes and functionalities.
• Metal-Organic Framework (MOF) Precursor: Acts as an organic ligand for creating novel MOFs, where the ethynyl groups can coordinate with metal ions or be further functionalized.
• Cross-Linking Agent for Polymers: Utilized to introduce rigid, aromatic nodes into polymer backbones via click chemistry (e.g., copper-catalyzed azide-alkyne cycloaddition), enhancing thermal stability and mechanical properties.
• Organic Semiconductor Materials: Employed in the development of π-conjugated systems for applications in organic light-emitting diodes (OLEDs), field-effect transistors (OFETs), and photovoltaic cells.
• Dendrimer and Hyperbranched Polymer Core: Functions as a central core molecule for the iterative synthesis of dendrimers with precise molecular architecture.
• Surface Functionalization: Used to modify material surfaces (e.g., graphene, nanoparticles) with ethynyl groups for subsequent attachment of other molecules.
• Research & Development: A valuable tool in academic and industrial R&D for exploring new materials with specific electronic, optical, or catalytic properties.
