Abstract

In this paper, we examine the transport properties of a 1,2,3-triazolium-based poly(ionic liquid) (PIL) at ambient and elevated pressure up to 475 MPa. We show that the isothermal and isobaric conductivity measurements analyzed in the 3D plane give a unique possibility to estimate the thermodynamic (isothermal compressibility and thermal expansion coefficient) properties for PILs having a charge transport fully controlled by viscosity. This result, providing a direct connection between thermodynamic and dynamic properties of PILs, is of significant importance for both material scientists and practical applications.

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.
