As a novel class of green functional materials and benign solvents with unique properties, ionic liquids (ILs) have been attracted increasing attention. It is indispensable to understand the structure-property relationships of ILs from the viewpoints of muhiscale. To bridge the electronic, atomistic/molecular and mesoscopic scales across several orders-of-magnitude in length and time, the molecular simulation are performed on the way. The muhiscale structures of IL have been studied and analyzed by using the computational chemistry. The approaches of quantum mechanics (QM), molecular dynamics (MD), computational fluid dynamics (CFD) and experimental measures have been performed to validate and support the quantitative structure-property relationships of ILs. On the above basis, the more and more applications of ionic liquids in process engineering, energy sources, environments and materials are expected.
