Abstract
Poly (ionic liquid)s (PILs) are innovative ionic materials, in which Ionic Liquids (ILs) are covalently joined by a macromolecular backbone. This opens a new field of Materials Chemistry that combines the versatility of ILs with the properties of polymers such as processability, control of hydrophobicity, crosslinking and more. 1,2,4-Triazolium-based PILs have recently received lots of attention due to their different types of applications, including catalysis, carbon capture, metal capture and many more. This diversity is based on the acidic nature of the protons in the cationic 1,2,4-Triazolium ring and the ability to generate carbenes under mild alkaline conditions, similar to other N-heterocyclic compounds. Until now, publications on 1,2,4-Triazolium-based materials are built primarily on monomers with a vinyl group attached directly to the 1N position of the 1,2,4-Triazolium unit. However, these monomers show low reactivity towards other comonomers, making them unsuitable for copolymerization and hyper crosslinked materials.
We envision that alternating the polymerizable unit on the 1N position, specifically a vinylbenzyl unit, will improve the copolymerization process with other styrenic comonomers or crosslinkers. Furthermore, the vinylbenzyl unit generates additional acidic sites in the monomer that could be used for catalytic systems. Until now only a limited number of these materials have been reported. We recently designed a template to synthesize porous styrenic 1,2,4-Triazolium-based networks carrying different functional groups. The latter renders the networks highly versatile so that they can be adjusted and tuned for different types of applications.
