Polymer‐encapsulated silica : An imidazolium‐based room‐temperature ionic liquid (PyC 12 MIM + Br − ) bearing a terminal pyrrole group was synthesized. Using this novel polymerizable surfactant as a template in a sol–gel process, highly ordered hexagonal mesoporous silica, containing aligned superlong polypyrrole nanowires, was successfully fabricated within the silica channels (see picture).
