General 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.

Application

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 1,1′-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.
exo-5-Norbornenecarboxylic acid can be used as a precursor in the synthesis of:
  • 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.

Multimode interference (MMI) and self-imaging are important phenomena of diffractive optics with major applications in signal processing, beam shaping, and optical sensing. Such phenomena generally arise from interference of normal modes in lossless dielectric guiding structures; however, the impact of

Reducing burst effects, providing controlled release, and safeguarding biologics against degradation are a few of several highly attractive applications for microgels in the field of controlled release. However, the incorporation of proteins into microgels without impairing stability is highly challenging.
