Hydrogen-bonded organic frameworks (HOFs) represent an interesting type of polymeric porous materials that can be self-assembled through H-bonding between organic linkers. To realize permanent porosity in HOFs, stable and robust open frameworks can be constructed by judicious selection of rigid molecular building blocks and hydrogen-bonded units with strong H-bonding interactions, in which the framework stability might be further enhanced through framework interpenetration and other types of weak intermolecular interactions such as π⋯π interactions. Owing to the reversible and flexible nature of H-bonding connections, HOFs show high crystallinity, solution processability, easy healing and purification. These unique advantages enable HOFs to be used as a highly versatile platform for exploring multifunctional porous materials. Here, the bright potential of HOF materials as multifunctional materials is highlighted in some of the most important applications for gas storage and separation, molecular recognition, electric and optical materials, chemical sensing, catalysis, and biomedicine.

多功能多孔氢键有机框架材料

氢键有机框架（HOF）代表了一种有趣的聚合物多孔材料，可以通过有机接头之间的 H 键进行自组装。为了实现 HOF 的永久孔隙率，可以通过明智地选择刚性分子构建单元和具有强 H 键相互作用的氢键单元来构建稳定和稳健的开放框架，其中框架稳定性可以通过框架互穿和其他类型的弱分子间相互作用（如 π⋯π 相互作用）进一步增强。由于 H 键连接的可逆性和柔性特性，HOF 表现出高结晶度、溶液加工性、易愈合和纯化。这些独特的优势使 HOF 可用作探索多功能多孔材料的高度通用平台。在这里，HOF 材料作为多功能材料的巨大潜力在气体储存和分离、分子识别、电和光学材料、化学传感、催化和生物医学等一些最重要的应用中得到了凸显。
