The unique characteristics of ILs endow them with great potential for applications in different fields including chem- ical reactions, extraction and separation, material science, renewable energy, environment, and photoelectric trans- formations. Their properties can be tuned to suit various applications by changing the structures of the cations and/or anions.展开更多
