The anion impact on the self-assembly of naphthalene diimide diimidazolium salts
Naphthalene diimide diimidazolium salts differing for the anion nature were synthesized and their properties as well as
their self-assembly behaviour were investigated. In particular, we took into consideration the N,N’-bis-(1-octyl-3-
propylimidazolium)-naphthalene diimide cation and anions differing in size, shape and coordination abilities like [I-], [BF4
-]and [NTf2-]. After determination of thermal behaviour, using differential scanning calorimetry and thermal gravimetric
