eng	Ionic liquids containing vanadium	Ionic liquids (ILs) are salts with relatively low melting points (<100 °C). They offer several advantages compared to conventional organic solvents such as non-volatility and non-flammability. Their physical-chemical properties are tunable through the modification of either the cation or the anion [1]. ILs commonly exhibit catalytic activity, being used as a combination solvent/catalyst. For instance, a tricomponent system has been studied as a more sustainable option compared to the commonly used amine/epoxide system. Vanillin-based epoxide resins in combination with succinic acid and imidazolium-based IL have been cured without need for a co-solvent, co-catalyst or conventional polymerization initiator [2]. ILs containing transition metals are also comprehensively studied. For example, 1-butyl-3-methylimidazolium heptachloridodiferrate, (Bmim)[Fe2Cl7], shows promising catalytic activity towards the copolymerization of limonene oxide with cyclic anhydrides [3]. Vanadium-based ILs were only sparsely studied. An IL containing vanadium in the form of a metavanadate anion and was studied as liquids for electrochromic cells fulfilling the role of both the electrochrome and the electrolyte [4].
