A new family of zwitterionic liquids arising from a phase transition of ammonium inner salts containing an ether bond
Aliphatic and alicyclic ammonium inner salts containing an ether bond were prepared as a new family of zwitterionic liquids. Ether bond is not only effective for lowering melting points of ammonium-type zwitterions but also interesting to realize unique solid-solid transition.
