Abstract

Front Cover: 1,2,3‐Triazolium‐based poly(ionic liquid)s are prepared by a solvent‐ and catalyst‐free monotopic approach based on thermal polyaddition of an α‐azide‐ω‐alkyne and in‐situ quaternization of the resulting 1,4‐/1,5‐disubstituted poly(1,2,3‐triazole) s. While a significant reduction in time, number of synthetic and purification steps is achieved, the resulting ion conducting materials have properties comparable to their pure 1,3,4‐trisubstituted regioisomers. Further details can be found in the article by M. M. Obadia, B. P. Mudraboyina, I. Allaoua, A. Haddane, D. Montarnal, A. Serghei, and E. Drockenmuller* on page 794.

Triethylene glycol-based poly(1,2,3-triazolium acrylate)s with enhanced ionic conductivity

“…[24][25][26][27] In general, for comparable substituents and anions, PTIL acrylates have lower T g and comparable T d10 values compared to PTIL ionenes. In agreement with previously described PTILs, the highest thermal stability is obtained for PTIL 9 which contains bis(trifluoromethane)sulfonimide (TFSI) counter anion.…”

“…20,21 A broad library of PILs has been established by combining cationic moieties (e.g. [23][24][25][26][27][28][29][30][31] Thanks to the robustness of the developed synthetic routes, a significantly broad library of PTILs with high thermal stability, low T g and high ionic conductivity has been developed through extensive macromolecular design, combinations of different anions, polymer backbones and architectures thus unfolding the potential of this new family of PILs. halides, sulfonates, carbonates, inorganic fluorides, perfluorinated sulfonimides, tricyanomethanide or dicyanamide).…”

“…ammonium, pyridinium, imidazolium, pyrrolidinium, phosphonium or 1,2,3-triazolium) with anionic counterparts (e.g. PTIL ionenes obtained by step growth polymerization, [23][24][25][26] as well as polyacrylate, 27 polystyrene, 28 poly(vinyl ester), 31 and poly-(4vinyl-1,2,3-triazolium), 18,32 PTILs obtained by chain growth polymerizations have been reported so far. Cationic PILs having free counter anions have been predominantly explored compared to their anionic and zwitterionic analogues.…”

Poly(1,2,3-triazolium)s: a new class of functional polymer electrolytes

“…Anticipating the orthogonal character of the polyaddition via thermal azide-alkyne Huisgen cycloaddition (TAAC) and Nalkylation of 1,2,3-triazoles, we have proposed the accelerated synthesis of linear main-chain TPILs using a monotopic approach under solvent-and catalyst-free conditions. 100,102,103 In the scope of scaling up and reducing the number of synthesis and purification steps, the principle of this one-step approach relies on the combination of TAAC polyaddition with in-situ N-alkylation of the resulting PTs using a broad range of alkylating agents (e.g. alkyl halides 19,97,98, CH 3 TFSI 35, trimethylphosphate 99 or methyl methanesulfonate 100).…”
