BeschreibungTrioctylphosphine (also known as Tri-n-octylphosphine, abbreviated as TOP) is a weakly basic organophosphorus compound that can be used in the synthesis of nanomaterials (such as metallic nanoparticles). It also serves as the most popular organophosphorus source in oil-phase synthesis, a stabiliser for certain nanorods, and acts as a solvent in certain chemical processes.

VerwendenTri-n-octylphosphine is used for coating zinc sulfide shells on cadmium-selenium quantum dot core by successive ionic layer adsorption and reaction method. It acts as a precursor to trioctylphosphine oxide. Further, it is used as a solvent for cadmium and selenium precursors. It also serves as a common reagent in the chemical synthesis of nanoparticles. It acts as a precursor to trioctylphosphine oxide.
