Poly(ionic liquid)s (PILs) are polymers

including ionic liquid (IL) moiety in repeating units

which combine the stability of polymer and the excellent properties of ILs. More recently

porous PILs

combining the advantages of functional IL units with porous structure

have showed wide applications in polymer chemistry

organic chemistry

electrochemistry and energy science fields. This review focused on the preparation of porous PILs and their applications in smart responsive materials

wastewater treatment materials

high efficiency catalysis

porous carbon materials and biomedical materials.
