我们已经成功地制备了具有不同极性的离子液体（ILs）的稳定的纳米分离的混合物。由于不混溶IL的简单组合形成稳定的宏观相分离，因此使用精心设计的两性离子型IL来稳定具有不同极性的两种不同IL的纳米偏析。这些混合物的纳米偏析揭示了通过X-射线测量和形成的高和低极性离子液体的稳定的纳米结构域被证实通过溶剂化显色的染料，选择单独溶解在高或低极性域。在本研究中，新提出了在高极性和低极性离子液体之间形成巨大面积的界面。
We have succeeded in preparing stable nano-segregated mixtures of ionic liquids (ILs) having different polarities. Since a simple combination of immiscible ILs forms stable macroscopic phase separation, a well-designed zwitterionic-type IL was used to stabilise nano-segregation of two distinct ILs with different polarities. Nano-segregation of those mixtures was revealed by the X-ray measurements and the formation of the stable nano-domains of highly and low polar ILs was confirmed by solvatochromism of dyes that were selected to solely dissolve either in highly or low polar domains. Formation of a huge area of interface between highly and low polar ILs has been newly proposed in the present study.
