瓜环-金属离子配位作用驱动的瓜环基框架

Cucurbit[n]urils-based Frameworks Driven by Cucurbit[n]urils-Metal Ion Coordination Interaction

自金属有机框架和配位网络概念提出以来,以连接简单结构单元方式形成周期性多孔框架为基本原理,构筑新型结构多孔框架和性能研究使网状化学及其应用得到了显著的发展。具有两个端口的刚性空腔使瓜环(Q[n]s)适合作为与Q[n]/金属离子(M^(z+))配合物相关框架的构筑单元。根据Q[n]/M^(z+)配合物的类型,对实验室近年来在瓜环与金属离子配位驱动构筑的瓜环基框架及其功能性质方面的内容进行较为全面的归纳和总结。构建与Q[n]/M^(z+)配合物相关框架不仅可以获得不同优雅结构的框架结构,更重要的是为探索其在吸附分离、检测、催化等方面的实际应用提供理论依据和实践依据。

Since the concepts of metal organic frameworks and coordination networks were proposed,based on the principle of connecting simple building units to generate periodic porous frameworks,the construction of novel structural porous frameworks and the study on their properties have led to significant developments in reticular chemistry.A rigid cavity with two opening portals make cucurbit[n]urils(Q[n]s)suitable as the building units for frameworks related to Q[n]/metal ion(M^(z+))complexes.According to the type of Q[n]/M^(z+) complexes,this paper made a more comprehensive summary of the construction and functional properties of cucurbit[n]urils-based frameworks driven by cucurbit[n]urils-metal ions coordination interaction studied in recent years.Then the construction of frameworks related to Q[n]/M^(z+) complexes could not only obtain elegant framework structures,but provide theoretical and practical basis for exploring practical application in adsorption separation,detection,catalysis,etc.
