Low viscosity ionic liquids

摘要

Disclosed is an ionic liquid:; wherein: n is 1 or 2; R¹ is selected from H and (C₁-C₆)alkyl; R² is selected from —(CH₂)_wO[(CH₂)_xO(CH₂)_y]_m(CH₂)_zCH₃ and ; wherein w is 1 to 6, x is 1 to 6, y is 0 to 6, z is 0 to 6, m is 0 to 3 and [w+m(x+y)+z] is less than or equal to 12; and R³ is selected from H and methyl, wherein if n is 1 then R³ is methyl, and if n is 2 then R³ is H. ;Also disclosed are electrochemical devices and devices employing such electrochemical devices as energy sources.
