以氢氧化钠为相转移剂，十二烷基硫醇为催化剂，将3-巯基丙酸（MPA）封端的水溶性ZnS：Mn ~（2+）配合物成功地转移到有机相中。即使在单一水相体系中，MPA配体也可以完全被长链硫醇取代。提出了将1-十二烷硫醇转化为1-十二烷硫醇可以降低配体交换过程中相关反应的吉布斯自由能，从而允许完全的配体交换反应和水溶性硫醇高效地转移到有机相中。此外，水溶性ZnS：Mn ~（2+）掺杂体系的表面态发光在进入有机相后受到了很大的抑制。
The 3-mercaptopropionic acid (MPA) capping water-soluble ZnS:Mn2+nanocrystal was successfully transferred into organic phase by using 1-dodecanethiol in presence of sodium hydroxide as phase-transfer agent. The MPA ligand can be replaced completely by the long chain thiol even in a single water phase system. It is proposed that the conversion of 1-dodecanethiol into 1-dodecnethiolate can reduce the Gibbs energy of the reactions concerned in the ligand-exchange process, thus allowing complete ligand-exchange reaction and highly efficient transfer of the water-soluble nanocrystal into organic phase. In addition, the surface state related luminescence of the water-soluble ZnS:Mn2+nanocrystal is suppressed greatly after being transferred into organic phase.
