Description

Silane, 1,1'-[3,4-Bis[2-(Trimethylsilyl)Ethynyl]-3-Hexene-2,5-Diyne-1,6-Diyl]Bis[1,1,1-Trimethyl- is a highly specialized, multi-functional organosilicon compound featuring a unique conjugated diyne and ethynylsilane architecture. This molecular structure makes it a critical building block for advanced materials science, particularly in the synthesis of complex molecular scaffolds and polymers with tailored electronic or optical properties. It is primarily sought after by researchers and manufacturers in organic electronics, photonics, and specialty polymer development who require precise, high-purity precursors for cutting-edge applications.

Application

• Advanced Organic Semiconductor Synthesis: Serves as a key monomer or cross-linking agent for creating conjugated polymers and small molecules used in OLEDs, OFETs, and photovoltaic cells.
• Molecular Wire and Nanostructure Fabrication: Utilized in bottom-up approaches to construct rigid, linear molecular frameworks and acetylenic scaffolding for nanotechnology.
• Specialty Silicone & Hybrid Polymer Development: Acts as a functional cross-linker or chain extender to introduce acetylenic groups into silicone polymers, enhancing thermal stability or enabling further chemical modification.
• Photonics and Nonlinear Optical (NLO) Materials: The extended π-conjugated system derived from its structure is valuable for developing materials with specific light-manipulating properties.
• Metal-Organic Framework (MOF) and Covalent Organic Framework (COF) Linkers: Used as an organic linker precursor to create porous materials with integrated silicon and acetylenic functionalities for gas storage or catalysis.
• Surface Modification and Coupling Agent: Can be employed to functionalize inorganic surfaces (e.g., silica, metals) with reactive ethynyl groups for subsequent "click chemistry" or other conjugation reactions.
• Academic and Industrial R&D: A valuable reagent for exploratory synthesis in organic and organometallic chemistry to create novel molecular architectures.
