A hollow victory : A multifunctional polymerizable ionic liquid (IL)‐based surfactant is used in the synthesis of silica spheres with tunable size. Hollow capsules with a mesoporous polymer‐network shell and pendant IL moieties are then fabricated by template synthesis (see picture). The pore size of the shell is reversibly adjustable by exchange of counteranions (blue and red circles) of the pendant IL units.
