Vaporisation of a dicationic ionic liquid

Chemphyschem. 2009 Feb 2;10(2):337-40. doi: 10.1002/cphc.200800690.

Abstract

Highest heat of vaporization yet: The dicationic ionic liquid [C(3)(C(1)Im)(2)][Tf(2)N](2) evaporates as a neutral ion triplet. These neutral ion triplets can then be ionised to form singly and doubly charged ions. The mass spectrum exhibits the dication attached to one remaining anion, and the naked dication itself (see picture).
