氢键有机骨架材料(Hydrogen organic frameworks,简称HOFs)是一类高度有序的新型多孔晶态材料,通过氢键,π-π堆积以及Van der Waals相互作用将主要是由轻元素(如C、H、N等)组成的离散的有机小分子结构单元自组装而成.该材料不仅具有高比表面积,多孔性,低密度,结构可预测性与结构可调节性的特点,而且还具有温和的合成条件,溶液可加工性和易再现性的独特特性,近年来引起了科学家们的广泛关注.本文简述了近几年来HOFs的合成方法及相关的应用,如气体吸附和分离、重金属检测、质子传导、催化、荧光传感等,并对目前存在的问题和应用前景进行了总结和展望.
Synthesis and Properties of Hydrogen Organic Frameworks
Hydrogen Organic Frameworks(HOFs)are a class of highly ordered new porous crystalline materials that self-assemble discrete organic small molecular structural units mainly composed of light elements(such as C,H,N,etc.)through hydrogen bonding,π-πstacking,and Van der Waals interactions.This material not only has the characteristics of high specific surface area,porosity,low density,structural predictability and adjustability,but also has unique characteristics such as mild synthesis conditions,solution processability,and easy reproducibility,which have attracted widespread attention from scientists in recent years.This article briefly describes the synthesis methods and related applications of HOFs in recent years,such as gas adsorption and separation,heavy metal detection,proton conduction,catalysis,fluorescence sensing,etc.,and summarizes and prospects the current problems and application prospects.
