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 tunable 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
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 tunable structures and functional channels. They have some of the 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
