Functional Ionic Liquids (FILs)
Ionic liquids (ILs) are kind of unconventional ionic salts also including cation and anion (Fig. 1a), which present as liquid form generally under 100 oC or lower temperature such as room temperature (room temperature ionic liquid, RTIL) [1]. Functional ionic liquids (FILs) (Fig. 1b), also being called task-specific ionic liquids (TSILs), possess specific structure with some functional sites introduced on the anion or cation and show special features and functions.
