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.
制备了单脲功能化的支柱[5]芳烃,表现出异常的脲行为。研究表明,它们在溶液中形成了具有较差阴离子结合能力的伪[1]轮烷,而在固态下形成了具有异常脲结构的[c2]雏菊链。
