abstract = {Three selenoether-functionalized ionic liquids (ILs) of
N-[(phenylseleno)methylene]pyridinium (1), N-(methyl)- (2)
and N-(butyl)-N‘-[(phenylseleno)methylene]imidazolium (3)
with bis(trifluoromethanesulfonyl)imide anions ([NTf2]) were
prepared from pyridine, N-methylimidazole and
N-butylimidazole with in situ obtained phenylselenomethyl
chloride, followed by ion exchange to give the desired
compounds. The crystal structures of the bromide and
tetraphenylborate salts of the above cations (1-Br, 2-BPh4
and 3-BPh4) confirm the formation of the desired cations and
indicate a multitude of different supramolecular
interactions besides the dominating Coulomb interactions
between the cations and anions. The vaporization enthalpies
of the synthesized [NTf2]-containing ILs were determined by
means of a quartz-crystal microbalance method (QCM) and
their densities were measured with an oscillating U-tube.
These thermodynamic data have been used to develop a method
for assessment of miscibility of conventional solvents in
the selenium-containing ILs by using Hildebrandt solubility
parameters, as well as for modeling with the electrolyte
perturbed-chain statistical associating fluid theory
(ePC-SAFT) method. Furthermore, structure–property
relations between selenoether-functionalized and similarly
shaped corresponding aryl-substituted imidazolium- and
pyridinium-based ILs were analyzed and showed that the
contribution of the selenium moiety to the enthalpy of
vaporization of an IL is equal to the contribution of a
methylene (CH2) group. An incremental approach to predict
vaporization enthalpies of ILs by a group contribution
method has been developed. The reaction of these ILs with
zinc acetate dihydrate under microwave irradiation led to
ZnSe nanoparticles of an average diameter between 4 and 10
nm, depending on the reaction conditions},
