氢键有机框架的合成与应用进展

Synthesis and Application of Hydrogen-Bonded Organic Framework

氢键有机骨架材料(Hydrogen-bonded Organic Frameworks,HOFs)是一类新兴的多孔晶体材料,通常由小分子有机结构单元通过氢键连接而自组装形成,具有良好结构的构建,π-π相互作用和静电吸引等引入,解决了氢键作用力弱、方向性差的问题,提高了HOFs材料的稳定性,实现了永久空隙的获得。此类独特的优势,让HOFs材料成为一种高度通用的平台,用于对多孔材料多功能的探索。在此重点概述了近年来HOFs材料在气体储存和分离、分子分离与识别、质子传导、生物医疗、异相催化等领域的重要进展。

Hydrogen-bonded organic frameworks(HOFs)are an emerging class of porous crystalline materials.It is usually formed by the self-assembly of small molecular organic building blocks through hydrogen bond.It has the construction of good structure,the introduction ofπ-πstacking interaction and electrostatic attraction,etc.,which solves the problems of weak hydrogen bonding force and poor directionality,improves the stability of HOFs materials,and realizes the acquisition of permanent voids.Such unique advantages make HOFs a highly versatile platform for exploring the multifunctionality of porous materials.Herein,we focus on the important progress of HOFs in the fields of gas storage and separation,molecular separation and recognition,proton conduction,biomedicine,and heterogeneous catalysis in recent years.
