摘要

Recently,crystalline porous materials such as metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) have attracted much interest not only in chemistry but also in materials science due to their ttmable structures and functional channels.They have some inherent disadvantages of being difficult to solution process and recovery,which might limit their wide usage.As a new kind of porous crystals,hydrogen-bonded organic frameworks (HOFs) have provided the solutions on these aspects attributed to their easy regeneration and mild reaction conditions [1].However,most HOFs are unstable and cannot sustain solvent removal,heat and/or humidity treatments because of the weak non-covalent hydrogen bonding and π-π stacking interactions to construct the frameworks.Therefore,up to now only a few examples of permanently porous HOFs have been reported with the comparatively low BET surface areas.This big problem has limited the further development of HOFs for their practical applications.
