| Title: |
A Temperature-Driven Reversible Phase Transfer of 2-(Diethylamino)ethanethiol-Stabilized CdTe Nanoparticles |
| Abstract: |
By changing the temperature, we found that DEAET-stabilized CdTe nanoparticles could transfer reversibly from the aqueous phase to the organic phase, which opens up a whole new set of applications in which the nanoparticles could be used to transport material between organic and aqueous phases. Theoretically, and experimentally, we found that DEAET molecules, by themselves show no such phase transfer. Compared to DEAET molecules, the different phase transfer behavior of CdTe NPs is ascribed to their size effects, which are large enough to disturb the hydrogen bonding of water surrounding NPs and thus increase the solubility in water.
