动态配位空间的构筑与调控

Construction and Modulation of Dynamic Coordination Space

"配位空间"(Coordination Space)是无机-有机杂化体系中的构筑基元通过配位键连接形成的具有特定结构和功能的空间。这一概念为基于配位键的框架体系的定向构筑与结构-性能调控提供了新的视角。作为典型的无机-有机杂化材料,金属-有机框架(Metal-Organic Framework,MOF)及金属有机笼(Metal-Organic Cage,MOC)等近年来受到广泛关注。这类材料的构筑与性能调控的核心可以认为是对其配位空间的结构设计与性能调控。具有刺激响应性的MOF可展现动态的配位空间,使其在吸附分离、传感、药物投递等方面具有重要的应用前景。本文将以动态金属有机框架的相关研究为基础简述动态配位空间研究的近期进展,包括其动态行为产生的结构基础、诱发因素及相关性能,归纳结构-性能的关系,为相关研究提供参考。

“Coordination space”is the space with specific structure and functions,which is defined by the coordination bonded structural elements of inorganic-organic hybrid system. This concept provides a new perspective for the research on the targeted construction and modulation of coordinative hybrid materials. As typical inorganic-organic hybrid materials,Metal-Organic Framework ( MOF) and Metal-Organic Cage ( MOC) have attracted widespread attention in recent years. The key point of targeted construction and regulation of could be regarded as the design of their coordination space. The stimuli-responsive MOFs possess dynamic coordination space,which promote their potential applications in adsorption /separation,sensing,drug delivery,and related fields. Based on the well - developed research of dynamic of metal-organic framework,herein we briefly introduce the recent progress in dynamic coordinate space,including the structure foundation and stimulating factors for the achievement of dynamic behaviors,the relationship between the structure and properties of this kind of material,which could be instructive useful references for related research investigation.
