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.
