Descrição
The potential utility of room temperature ionic liquids as
electrolytes in current electrochemical applications has been
explored. Hence, the electrochemical behavior of [Ni(tmc)]Br2
complex at a glassy carbon electrode in the absence or in the
presence of unsaturated halides in the ionic liquids, 1-ethyl-3-
methylimidazolium ethylsulfate, [C2mim][C2SO4] and N,N,Ntrimethyl-
N-(2-hydroxyethyl) ammonium
bis(trifluoromethylsulfonyl)imide, [N1 1 1 2(OH)][NTf2], has been
examined by cyclic voltammetry. It was observed that
[Ni(tmc)]2+ complex is reduced in a reversible one-electron step
and the electrogenerated [Ni(tmc)]+ complex catalytically reduces
the carbon-halogen bond of unsaturated halides.
The potencial use of natural ionic conducting polymer
matrixes was also investigated. Samples of natural
macromolecules-based electrolytes with the ionic liquid 1-ethyl-
3-methylimidazolium ethylsulfate, [C2mim][C2SO4], were
prepared and characterized. The preliminary studies carried out
with electrochromic devices (ECDs) incorporating optimized
compositions have confirmed that these materials may perform as
satisfactory multifunctional component layers in the field of
ECD-based devices.
