| Abstract: | Herein, we report our observations on voltammetric investigations about the redox behaviour of para‐nitrotoluene, 1,4‐benzoquinone and ferrocene, aimed at exploring the unusual aspects of ion‐pairing phenomena in imidazolium‐based room temperature ionic liquids (RTILs). Our observations indicate that the stabilization of electrogenerated ion/radical ion intermediates depends upon the potential of the working electrode and the overall composition of RTILs. In light of observed relative trends and quantum mechanical calculations, we propose that the ion‐pair stabilization of electrogenerated charged species in RTILs is closely related to the structural organization and composition of electrode/RTIL interface.
