Description
Summary:[Display omitted] •Novel oligo(oxyethylene)-functionalized thiazolium based ionic liquids were synthesized.•Target compounds are liquid at room temperature.•Good thermal stabilities.•Good ionic conductivities. Two series of thiazolium bis(trifluoromethylsulfonyl)imide [NTf2] room temperature ionic liquids (RTILs) functionalized with oligo(oxyethylene)-chains have been synthesized in multigram scale and characterized. Their thermal properties and conductivity values have been determined. The increase in the number and length of the oligo(oxyethylene)-chains attached to the thiazolium ring resulted in lower values of ionic conductivity.
