title: The self-complexation of mono-urea-functionalized pillar[5]arenes with abnormal urea behaviors.
abstract: Mono-urea-functionalized pillar[5]arenes were prepared which exhibited abnormal urea behaviors. They were shown to form pseudo[1]rotaxanes with poor anion binding abilities in solution and [c2]daisy chains with an abnormal urea motif in the solid state.
