â¢A novel family of salts based on highly-delocalized amidinium cations and anions were synthesized.â¢The salts are hydrophobic, room-temperature ionic liquids and highly miscible in non-polar media.â¢The salts show electrochemical activity and ionic conductivities that span over a wide range from 10â 11 to 10â 4 S.cmâ 1.â¢The salts can be used as antistatic agents or as new type of hydrophobic electrolytes in electrochemical devices.
There is little known about electrochemical behavior in non-polar media due to lack of compatible, hydrophobic salts. In this work, this difficult challenge has been overcome by following a strategy based on designing and synthesizing a novel family of organic salts with highly-delocalized cations and anions. The salts are based on the amidinium cation with highly-delocalized positive charge and long alkyl groups that enable good miscibility in heptane, an archetypical, non-polar media, while being hydrophobic, room-temperature ionic liquids. The electrolyte solutions show ionic conductivities that span the range 10â 11-10â 4 S cmâ 1 and electrochemical activity which enable their application as antistatic agents and also as new type of hydrophobic electrolytes in various electrochemical devices.
