摘要
芳炔大环是由芳(杂)环和炔键构成的具有规整多边形环状分子结构的化合物,自问世以来即受到化学家和材料学家的广泛关注。芳炔大环具有不会坍塌的刚性骨架,环上特定位置可带有柔性侧链或取代官能团,环平面上大的π电子共轭体系和环上灵活的结合点赋予芳炔大环独特而有趣的超分子性质。本文对芳炔大环的超分子性质作了综述,从大环在溶液中的缔合、热致液晶性质、一维超分子自组装及在基底表面或固-液界面二维自组装4个方面展开评述,介绍了研究方法,着重讨论了分子结构与物质性质的关系,并对芳炔大环的应用前景做了展望,为通过合理设计分子结构来制备满足尺寸、形状及功能要求的新型材料提供借鉴。
Arylacetylene macrocycles （AEMs） that contain shape-persistent backbones and allow the attachment of （functional） side groups at defined positions have attracted much attention since their invention. Due to the large w-conjugated system and the flexible bonding points at the ring, arylaeetylene macroeycles are especially valuable candidates for the construction of complex supramolecular architectures. This review covers the recent progress in the research on the supramoleeular properties of arylaeetylene macrocycles, including aggregation in solution, liquid crystal behavior, one-dimensional self-assembly and supramoleeular-assembled monolayer at the substrate surface or at the solid-liquid interface. The investigation method is introduced. The relationship between the molecular structure and the supramolecular property of AEMs are elaborated, and potential applications of AEMs are indicated. It will be helpful for the preparation of novel materials with desired size, shape and functionality through rational molecular design.
