Triazoliums are a family of five-membered heterocyclic cations that contain three nitrogen and two carbon atoms. In contrast to the widely studied imidazolium cations, triazoliums less explored. terms chemical structure, triazolium replaces atom in cation ring with an electron-withdrawing atom, which makes more polarized. Among many physical properties, thermal responsiveness is particular interest us but has been rarely investigated. this contribution, we prepared series 1,2,4-triazolium-based poly(ionic liquid)s (PILs) varying alkyl substituents counteranions their thermal-responsive behavior. We found 1,2,4-triazolim-based PILs polymeric backbone structure similar polyimidazoliums exhibited opposite phase transition processes solvents. For example, methyl-substituted upper-critical-solution-temperature (UCST)-type methanol when counterion was I
