氢键有机骨架材料的研究进展

Recent Advances in Hydrogen-bonded Organic Frameworks

多孔氢键有机骨架材料(Hydrogen-bonded Organic Frameworks,HOFs)是一类晶态的多孔聚合物,主要是由轻元素(C、H、O、N、B等)组成的有机小分子构筑单元通过氢键,π-π堆积以及范德华相互作用自组装而成。由于其具有较高的比表面积、多孔性、低密度和结构可调控等优势,兼备了金属有机骨架(MOFs,Metal Organic Frameworks)和共价有机骨架(COFs,Covalent Organic Frameworks)两类新型的多孔晶体材料的优点,近年来已经引起科学家们的广泛关注。本文从HOFs材料的基本构筑单元的设计出发,重点介绍了近几年HOFs材料在气体吸附与存储、气体分离以及传感等领域所取得的重要进展,并对该领域未来发展趋势进行了展望。

Hydrogen-bonded organic frameworks （HOFs）, as a novel class of crystalline porous crganic polymers, are mainly constructed by self-assembly of organic building blocks composed of light elements （C, H, O, N, B, etc. ） though hydrogen bonds, π-π stacking and van der Waals interactions. HOFs have both the advantages of the two new types of porous crystalline materials such as MOFs and COFs. Because of the high specific surface area, high porosity, low density and controllable structure, HOFs have attracted extensive attention in recent years. Herein, based on the design of building blocks used to construct HOF materials, the research progresses in recent years of HOF materials, including gas adsorption and storage, gas separation and sensing, are introduced in this up-to-the-minute review. Furthermore, the future development trend of this field is prospected.
