离子液体[C_6mim][PF_6]用于金纳米棒相转移研究

Research on the Application of Hydrophobic Ionic Liquid [C_6mim][PF_6] for a Phase Transfer to Gold Nanorods

合成了疏水性室温离子液体1-己基-3-甲基咪唑六氟磷酸盐([C_6mim][PF_6]),用于金纳米棒相转移试剂,结果发现其相转移能力很强且转移效率高,能实现水相中金纳米棒的相转移。这一新方法或思路不仅可实现金纳米棒的相转移,拓展其应用领域,而且可利用离子液体来处理包含金纳米棒的水相分散体系,实现纳米粒子的分离、回收或去除。

Hydrophobic ionic liquid 1-hexyl-3-methylimidazolium hexafluorophosphate([C_6mim][PF_6]) is prepared and used as a phase transfer reagent of gold nanorods, and the results show that it can effectively achieve the transfer of gold nanorods from the water phase to the hydrophobic ionic liquid phase. So the prepared ionic liquid not only can be used to realize phase transfer of nanoparticles for expanding its application field in new organic system,but also can separate, recover and remove the valuable nanoparticles in aqueous solution.
