Abstract

Abstract Synthesis of ionic liquids (IL) based on oxygen-containing spirobipyrrolidinium salts with BF 4, BF 3 C 2 F 5, and NTf 2 as counterions was undertaken. Their physical and electrochemical properties were evaluated for suitability for Room Temperature Ionic Liquids (RTIL) application. Reduction in melting point occurred upon exchange of C (2) by an O- atom of spirobipyrrolidinium, without sacrificing the electrochemical stability; while ...
