我们描述了一类新的超分子大环-联苯并[n]芳烃(n=3，4)的一锅法合成，独特的几何构型和有趣的主客体性质。设计和开发新型大环合成受体是超分子化学中一个永恒而富有挑战性的课题。在这里，我们描述了一类新的超分子大环-联苯并[n]芳烃(n=3，4)的一锅法合成，独特的几何构型和有趣的主客体性质，它们是由4，4‘-联苯酚或4，4’-联苯醚单元通过3-和3‘-亚甲基桥连接而成的。联苯大环可方便地访问/修改，并且对客户非常友好。特别的是，联苯[4]芳烃不仅能够与有机阳离子客体形成包合物，而且能够与中性的π-电子缺乏分子形成包合物。与取代单苯基的杯[芳烃]、间苯二酚、环三氢呋喃和柱芳烃相比，本文报道的联苯[n]芳烃在拓扑结构和识别性能上都具有明显不同的特点，因此在超分子化学等领域有着广泛的应用。
We describe the one-pot synthesis, unique geometries and intriguing host–guest properties of a new class of supramolecular macrocycles – biphen[n]arenes (n = 3, 4). To design and exploit novel macrocyclic synthetic receptors is a permanent and challenging topic in supramolecular chemistry. Here we describe the one-pot synthesis, unique geometries and intriguing host–guest properties of a new class of supramolecular macrocycles – biphen[n]arenes (n = 3, 4), which are made up of 4,4′-biphenol or 4,4′-biphenol ether units linked by methylene bridges at the 3- and 3′- positions. The biphenarene macrocycles are conveniently accessible/modifiable and extremely guest-friendly. Particularly, biphen[4]arene is capable of forming inclusion complexes with not only organic cationic guests but also neutral π-electron deficient molecules. Compared with calixarenes, resorcinarenes, cyclotriveratrylenes and pillararenes with substituted mono-benzene units, the biphen[n]arenes reported here possess significantly different characteristics in both their topologic structures and their recognition properties, and thus can find broad applications in supramolecular chemistry and other areas.
