Product Introduction

Oleylamine (CAS No. 112-88-9) is a long-chain primary fatty amine containing an 18-carbon unsaturated hydrocarbon chain and a primary amine group. Its amphiphilic structure provides both surface-active and coordinating properties, making it an important reagent and ligand in nanomaterial synthesis and materials chemistry.

Oleylamine is widely used in nanoparticle synthesis, colloidal nanomaterials, surface modification, catalysis, organic synthesis, and materials research. It can function simultaneously as a solvent, reducing agent, stabilizer, and surface ligand depending on the reaction system.

Its ability to coordinate with metal ions and bind to nanoparticle surfaces makes it particularly valuable for controlling particle size, morphology, dispersion, and surface chemistry.

Mechanism / Principle

Surface Ligand and Stabilization Function

Oleylamine contains a primary amine group capable of coordinating with metal ions and metal-containing surfaces, while its long hydrophobic chain provides steric stabilization.

In nanomaterial synthesis:

• The amine group can coordinate with metal precursors or nanoparticle surfaces.
• The hydrocarbon chain provides steric stabilization.
• Surface binding can limit uncontrolled particle aggregation.
• Reaction conditions involving Oleylamine can influence nucleation and crystal growth.
• Its dual role as ligand and reaction medium can affect nanoparticle morphology and size distribution.

This makes Oleylamine particularly useful for colloidal synthesis of metal, semiconductor, and metal oxide nanomaterials.
