exo-5-Norbornenecarboxylic acid Usage And Synthesis

Description

Exo-5-norbornenecarboxylic acid is a bicyclic compound that has potential applications in the field of material science due to its unique chemical properties. It is a versatile building block for the synthesis of various functional materials, including polymers, dendrimers, and self-assembled monolayers. It can be used to modify surfaces or to functionalize nanoparticles, influencing their optical, magnetic, or electronic properties. It is also often used in ring-opening metathesis polymerization reactions to form polymers with controlled molecular weight and structure. Additionally, exo-5-norbornenecarboxylic acid can function as a ligand for coordination chemistry and catalysis.

Uses

Exo-5-norbornenecarboxylic acid can be used as:

• A starting material in the synthesis of the metathesis polymer via a ring-opening metathesis polymerization (ROMP) reaction of the ester of exo-5-norbornenecarboxylic acid and 1,1μ-bi-2-naphthol.
• A monomer in the preparation of thin films via surface-initiated polymerization process. The resulting thin film serves as a template for selective deposition and etching of metal oxides, which is of significant importance in the microelectronic industry.

• Different crosslinkers for ring-opening metathesis polymerization.
• Norbornene-functionalized monomers, which are used to make poly(norbornene)s via ring-opening metathesis polymerization (ROMP).
• Hydrolytically cleavable and hydrolytically stable functionalized macromonomers for hydrogel preparation.
