The reversible phase transfer of 2‐(diethylamino)ethanethiol (DEAET)‐stabilized CdTe nanoparticles (NPs) in a mixture of water and toluene is driven solely by temperature (see picture). Theoretical studies reveal that the net hydrophobic force of these NPs decreases at high temperature, thus favoring the transfer of NPs into the aqueous phase.
