Research Abstract

We successfully synthesized a room-temperature ionic liquid made by combining a cobalt bis(dioxolene) complex dianion and a bulky tetraalkylphosphonium cation. Temperature denpendences of the electronic absorption spectra and static magnetic susceptibility revealed that the ionic liquid exhibits a valence-tautomeric equilibrium in the liquid state at around room temperature. We also synthesized 15 kinds of protic ionic liquids with different pK_a-pK_a' values, and found that the value intimately relates to the Walden product and solvatochromic parameters.
