1-Octadecene has been commonly used as a non-coordinating solvent for growing nanoparticles and quantum dots due to its high boiling point. The 1-octadecene monolayer is a promising passivating coating in nanoelectronics due to its stability and chemical protection against oxidation, effects of acids and bases without altering the properties.
