A 1,2,3-triazolate lithium salt with ionic liquid properties at room temperature

Author affiliations

Abstract

A triethylene glycol-based 1,2,3-triazolate lithium salt with ionic liquid properties at room temperature is synthesized in three steps including copper-catalysed cycloaddition between alkyne-functionalized monomethoxy-triethylene glycol and azidomethyl pivalate, followed by the deprotection of the methyl pivalate group and further lithiation of the 1H-1,2,3-triazole intermediate. The resulting lithium 1,2,3-triazolate is characterized by NMR spectroscopy, differential scanning calorimetry, thermogravimetric analysis, broadband dielectric spectroscopy, electrochemical impedance spectroscopy and cyclic voltamperometry. This approach provides new opportunities for the further development of highly functional molecular and macromolecular lithium salts.
