Does the Like Dissolves Like Rule Hold for Fullerene and Ionic Liquids?
(Springer, 2014-06-01)Over 150 solvents have been probed to dissolve light fullerenes, but with a quite moderate success. We uncover unusual mutual polarizability of C-60 fullerene and selected room-temperature ionic liquids, which can be applied ...
