Ethynyl-linked Dibenzaldehyde, identified by CAS Number 84907-55-1, is a fascinating organic molecule that serves as a critical building block in advanced materials synthesis, particularly for Covalent Organic Frameworks (COFs). Its unique structure, combining a rigid ethynyl core with two reactive aldehyde groups, offers significant advantages for creating porous, crystalline materials with tailored properties for diverse applications. As a dedicated chemical manufacturer and supplier in China, we are pleased to offer this high-purity compound to researchers and industrial clients worldwide.

The chemical structure of Ethynyl-linked Dibenzaldehyde consists of two benzaldehyde units linked by an ethynyl (acetylene) moiety. This molecular design imparts several key characteristics: the ethynyl group provides linearity and rigidity, promoting the formation of ordered, crystalline COFs, while the terminal aldehyde groups are highly reactive, readily undergoing condensation reactions with amines to form robust imine linkages. This facile reaction chemistry is fundamental to the synthesis of a broad range of imine-based COFs.

In terms of properties, Ethynyl-linked Dibenzaldehyde typically appears as a pale yellow powder. Its purity is a critical factor for its application in COF synthesis, as impurities can disrupt the polymerization process and affect the final material’s crystallinity and performance. We ensure our Ethynyl-linked Dibenzaldehyde is supplied at a high purity level, typically ≥98%, making it suitable for demanding research and development projects. We encourage potential buyers to inquire about our specifications and request a quote for bulk quantities.

The primary application driving interest in Ethynyl-linked Dibenzaldehyde is its use as a monomer for COFs. These porous organic materials have shown immense potential in areas such as:

  • Catalysis: COFs can host catalytic species or exhibit intrinsic catalytic activity due to their high surface area and tunable pore environments.
  • Gas Storage and Separation: The controlled porosity of COFs makes them excellent candidates for capturing and storing gases like CO2, H2, and CH4.
  • Biocatalysis: Enzymes can be effectively immobilized within COFs derived from this monomer, leading to more stable and reusable biocatalysts for chemical synthesis.
  • Fluorescent Materials: The conjugated backbone of COFs incorporating this monomer can lead to luminescent properties, useful in sensors and optoelectronic devices.
