由于这类系统所引起的耐人寻味的合成和结构问题，诸如伪轮烷、轮烷和环戊烷等螺纹状分子实体的生成目前是人们相当感兴趣的主题。21这一领域的最新发展包括在材料科学和超分子器件设计方面的潜在应用[31，例如新型聚合物复合材料[41和简单的机械分子过程]。[~~在轮烷的情况下，最初的合成策略侧重于统计制备方法，但最近利用分子间相互作用的超分子方法--如芳香族引力、[**61氢键、R71和金属离子配位[‘，81]--被发现对螺纹状分子是最有效的。包含金属离子的轮烷和假轮烷代表了一类特别有趣的超分子物种，它们可能显示出丰富的物理化学性质，如氧化还原、光学和磁性行为。金属离子定向穿线也可用于构建金属离子的线性阵列
The generation of threaded molecular entities such as pseudorotaxanes, rotaxanes, and catenanes is currently the subject of considerable interest owing to the intriguing synthetic and structural issues posed by such systems.[’. 21 Recent developments in this field include potential applications for materials science and the design of supramolecular devices [31 such as novel polymer composites [41 and simple mechanical molecular processe~.[~~ In the case of rotaxanes initial synthetic strategies focused on statistical methods of preparation, but more recently supramolecular approaches utilizing intermolecular interactions-such as aromatic attractive forces,[** 61 hydrogen bonding, r71 and metal ion coordination [’, 81-have been found to be most efficient for threaded molecules. Rotaxanes and pseudorotaxanes that incorporate metal ions represent a particularly interesting class of supramolecular species that might display a rich variety of physicochemical properties such as redox, optical, and magnetic behavior. Metal ion directed threading may also be used for constructing linear arrays of metal ions
