Abstract

We demonstrate control over the orientation of PbS nanoparticles by way of directed assembly, which in turn affects the crystal structure of alkylamine surfactants such as octadecylamine (ODA, C ₁₈H ₃₇NH ₂) and hexadecylamine (HDA, C ₁₆H ₃₃NH ₂). This directed assembly method results in the arrangement of PbS nanoparticles with a well-defined epitaxial orientation on lamellar alkylamine sheets, which undertake a new crystal structure to accommodate these relations. Understanding these surfactant-nanoparticle inter-relations is very instrumental in understanding surfactant-assisted nanoparticle synthesis and assembly.
