Abstract: Ionic liquids (ILs) and poly(ionic liquid)s (PILs) are known for their interesting characteristics, such as intrinsic ionic conductivity, high chemical, electrochemical and thermal stabilities, and low volatility. They constitute a versatile class of materials whose structure can be modified to yield a task-specific material with improved performance for a desired application. The physicochemical properties related to ionic transport can be tailored by modifying the cation and/or anion structure in addition to the polymeric matrix and spacer groups in the case of PILs. The properties can be improved for use in electrolytes and polymeric electrolytes for electrochemical devices such as rechargeable batteries and supercapacitors. ILs and PILs that possess good transport properties can be further functionalized to have electrochromic groups attached to their structure to construct electrochromic devices. In addition, these materials also present high selectivity for CO2 absorption, and can be modified to improve the capture capacity and separation efficiency. In this chapter, different aspects regarding the modification of ILs and PILs for different applications will be explored with a focus on the relationship between their structures and physicochemical properties, and the effect on their performance in different devices.
