液体的多孔性

Porosity in Liquids

简要介绍由James定义的多孔液体的概念。多孔液体,即具有永久孔洞的液体,通过刚性的主体分子和合适的窗口结构,把不需要的占据物阻止在孔洞外,因而保持孔洞空置使其它物质可以进入。动态多孔液体是指空腔被占据但仍具有多孔液体性质的液相物质。多孔液体结合了微孔固体的大小、形状选择性、吸附等特性和液体的快速传质性、流动性和稳定的动力学性能,具有重要的理论研究价值。

The concept of porous liquids or liquids with permanent micro-porosity proposed by James et al. is introduced. By using rigid host molecules with restricted access windows, any unwanted occupation of the pores could be prevented so that the pores could be kept empty and available. The concept of dynamic porous liquids is also proposed. In these liquids, the properties of porous liquids are still exhibited although the pores have been occupied. Porous liquids could combine properties of micro-porous solids with the rapid mass transfer, fluidity and fast kinetics of liquids.
